Three defects kept that claim from surviving to the call site. `mergeAndIntersectDeep` stored the receiver's deep set in the new `Concrete` while computing the hash from the intersected one, so equal exclusion sets disagreed on `hashCode` and every hash-keyed storage misbehaved. The four lineage-join sites -- the automata, cactus and tree side-effect requirement storages, and the summary side-effect merge -- joined with `union`. `union` composes refinements, and a deep entry is not one, so it now states that invariant as a `check` and the join sites call `mergeAndIntersectDeep`: plain entries union, deep entries intersect, because the join of a cleaned and an uncleaned lineage is uncleaned. `MethodCallSummaryHandler` passed `null` as the initial-fact exclusion when applying a summary edge, leaving the initial fact without the deep entries just attached to the exit fact and breaking the single-exclusion edge invariant. Separately, a trailing any-field modifier in a serialized condition (`arg(0).*`) lowered to a plain `ContainsMarkLiteral` over an `AnyAccessor` query, which matches nothing: an abstract fact reports its read mismatch without an accessor, so the refinement that unfolds the fact never fires. It is now normalised into `ContainsMarkOnAnyField`, which the existing any-field lowering handles.

The new suite holds the program, source, sink and read depth constant across each pair and varies only the cleaner position, which turns out to decide everything. Three positional pairs -- concrete `arg0`, `arg0.f`, `arg0.f.k` -- are green at every depth, including over an ABSTRACT any-field source, where the refinement splits the fact until the cleaner's path is concrete. A concrete clean is a node deletion, and the tree's branches keep `.raw` and `.val` apart through the summary merge. The starred pairs fail exactly where the answer depends on the star. Depth 1 is green and says nothing: the read is `p.val` itself, which the starred cleaner's base component removes as a concrete node. Depths 2 and 3 are the defect, and both fail in the false-positive direction -- their unsanitized siblings stay green, so no finding is lost. Four non-vacuity controls run each config with the cleaner deleted. They are red in Automata, which reports nothing on the `*CleanedFlow` entry points regardless of the cleaner, so all six of its `is silent` cases pass vacuously and are disabled with that as the reason rather than counted as coverage. The two `DeepCleanSummaryAnalysisTest` sibling cases are the same defect and get the same marking, pointing at the plan instead of at a storage-grouping stopgap that plan removes again. `:test` 700/0/19, `:opentaint-dataflow-core:opentaint-dataflow:test` 126/0/0. --- .../test/samples/DeepCleanSummarySample.java | 45 ++ .../CleanerFieldSensitivityAnalysisTest.kt | 402 ++++++++++++++++++ .../dataflow/DeepCleanSummaryAnalysisTest.kt | 26 +- 3 files changed, 470 insertions(+), 3 deletions(-) create mode 100644 core/src/test/kotlin/org/opentaint/jvm/sast/dataflow/CleanerFieldSensitivityAnalysisTest.kt diff --git a/core/samples/src/main/java/test/samples/DeepCleanSummarySample.java b/core/samples/src/main/java/test/samples/DeepCleanSummarySample.java index 3be264216..64563ff6c 100644 --- a/core/samples/src/main/java/test/samples/DeepCleanSummarySample.java +++ b/core/samples/src/main/java/test/samples/DeepCleanSummarySample.java @@ -54,4 +54,49 @@ public void cleanOnlyFlow(Box b) { Box r = wrapCleanOnly(b); sink(r.f); } + + public void sinkBox(Box b) { } + + public void boxCleanedFlow(Box b) { + Pair p = wrap(b); + sinkBox(p.val); + } + + public void boxUncleanedFlow(Box b) { + Pair p = wrap(b); + sinkBox(p.raw); + } + + public static class Leaf { + public String k; + } + + public static class Node { + public Leaf f; + } + + public static class NodePair { + public Node raw; + public Node val; + } + + public void cleanNode(Node b) { } + + NodePair wrapNode(Node b) { + NodePair p = new NodePair(); + p.raw = b; + cleanNode(b); + p.val = b; + return p; + } + + public void nodeCleanedFlow(Node b) { + NodePair p = wrapNode(b); + sink(p.val.f.k); + } + + public void nodeUncleanedFlow(Node b) { + NodePair p = wrapNode(b); + sink(p.raw.f.k); + } } diff --git a/core/src/test/kotlin/org/opentaint/jvm/sast/dataflow/CleanerFieldSensitivityAnalysisTest.kt b/core/src/test/kotlin/org/opentaint/jvm/sast/dataflow/CleanerFieldSensitivityAnalysisTest.kt new file mode 100644 index 000000000..1544ffbb9 --- /dev/null +++ b/core/src/test/kotlin/org/opentaint/jvm/sast/dataflow/CleanerFieldSensitivityAnalysisTest.kt @@ -0,0 +1,402 @@ +package org.opentaint.jvm.sast.dataflow + +import org.junit.jupiter.api.Disabled +import org.junit.jupiter.api.Test +import org.junit.jupiter.api.TestInstance +import org.opentaint.dataflow.ap.ifds.Accessor +import org.opentaint.dataflow.ap.ifds.ElementAccessor +import org.opentaint.dataflow.ap.ifds.FieldAccessor +import org.opentaint.dataflow.ap.ifds.access.AnyAccessorUnrollStrategy +import org.opentaint.dataflow.ap.ifds.access.ApMode +import org.opentaint.dataflow.configuration.jvm.serialized.PositionBase.Argument +import org.opentaint.dataflow.configuration.jvm.serialized.PositionBaseWithModifiers +import org.opentaint.dataflow.configuration.jvm.serialized.PositionModifier +import org.opentaint.dataflow.configuration.jvm.serialized.SerializedRule +import org.opentaint.dataflow.configuration.jvm.serialized.SerializedTaintAssignAction +import org.opentaint.dataflow.configuration.jvm.serialized.SerializedTaintCleanAction +import org.opentaint.dataflow.configuration.jvm.serialized.SerializedTaintConfig + +/** + * How field-sensitive a cleaner is across a summarized wrapper, as a function of how its position + * is written. + * + * Every case runs the same program shape. `wrap`/`wrapNode` stores its whole argument twice -- + * once before the clean (`p.raw`) and once after it (`p.val`) -- so both stores alias one object + * and the two summary edges leave from the same initial fact.

An abstract tree node gains an optional AbstractionExclusions: the starred sanitizer's residual claim that a mark is removed from whatever later materializes below the node. Each mark carries the minimal relative depth of the claim -- depth 2 at the cleaned base itself (a direct mark-child is the base action's job, mirroring the flat mechanism's minPruneDepth=2), depth 1 anywhere deeper. The annotation is part of node identity (equals/hash/interning) and of the join: merging two lineages at the same node intersects their claims at the weaker depth, with "not abstract" as the identity. The merge-delta contract carries the JOINED state when it changed, so a consumer merging the delta converges (intersect is idempotent and absorbing). The workhorse create() gained the annotation parameter WITHOUT a default, so every construction site states its decision explicitly: transforms and filters preserve, removeAbstraction and concat drop (the claim dies with the abstraction whose growth it constrained), merges join. Nothing constructs a non-null annotation yet; both suites at baseline (126/0/0, 700/0/19) and :test wall-clock is +2s on 2m20s -- far under the plan's 15% gate. Serialization deliberately still drops the annotation (todo Task 5): none exist until the cleaner starts producing them in Task 3. --- .../ifds/access/tree/AbstractionExclusions.kt | 136 ++++++++++++++++++ .../ap/ifds/access/tree/AccessTree.kt | 82 ++++++++--- .../access/tree/AccessTreeAnySuffixMatcher.kt | 2 +- 3 files changed, 201 insertions(+), 19 deletions(-) create mode 100644 core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/tree/AbstractionExclusions.kt diff --git a/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/tree/AbstractionExclusions.kt b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/tree/AbstractionExclusions.kt new file mode 100644 index 000000000..936b6a1d5 --- /dev/null +++ b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/tree/AbstractionExclusions.kt @@ -0,0 +1,136 @@ +package org.opentaint.dataflow.ap.ifds.access.tree + +import org.opentaint.dataflow.ap.ifds.access.util.AccessorIdx + +/** + * Excluded-mark annotation of an ABSTRACT [AccessTree.AccessNode]: a starred sanitizer's residual + * claim that a taint mark is removed from everything that later materializes below this node — by a + * summary delta concatenated onto it, or by demand-driven refinement growing through it. + * + * The claim lives on the abstract node and nowhere else.

Mon Sep 17 00:00:00 2001 From: Aleksandr Misonizhnik Date: Tue, 28 Jul 2026 13:45:49 +0200 Subject: [PATCH 36/66] fix(dataflow): the starred clean is field-sensitive across summaries (tree) The engine now uses the structural deep clean (Task 3 of the field-sensitivity plan): on `base.[any]`, the cleaner dispatches to `FinalFactAp.deepClean` -- concrete `![m]` nodes below the base are deleted, abstract nodes carry the residual claim -- with the legacy flat `excludeDeep` channel kept only for representations that do not support it (automata, cactus) until Task 6. Making the claim survive to the caller took three seams the plan had not named, each found by measurement on `cleanOnlyFlow`: - the empty-delta summary application never calls `concat`: it runs through `SummaryExclusionRefinement`, which carried only the exclusion set. The refinement now carries the empty delta, and appliers concat it, so the caller's claim transfers onto the transited summary's exit abstraction -- the structural counterpart of the flat design's exclusion-set preservation. `AbstractionExclusions.union` accumulates the caller's claim with the callee's own (both hold for one lineage; marks union at the stronger depth); - `splitOnMatching` classified ANY abstract exit as an identity edge, and the id-edge storage rebuilds its exit as the initial fact's PLAIN abstraction -- silently dropping the claim. An annotated abstraction no longer matches; such edges keep their real exit tree in the merging storage, whose `mergeAdd` join applies the intersection law; - the tree deep sweeps (`delta()`'s removeAccessors pass, the deep half of `AccessPath.filter`) are deleted: tree exclusion sets no longer carry deep entries, and enforcement lives at the concat attach points. The four red acceptance cases are green and re-enabled: both deep starred reads in CleanerFieldSensitivityAnalysisTest and both sibling cases in DeepCleanSummaryAnalysisTest -- with their unsanitized siblings and all four non-vacuity controls still green, so the claim blocks only what the sanitizer cleaned. Two new law tests pin the transit. `:test` 700/0/15 (the four re-enabled cases account for 19->15), wall-clock unchanged; dataflow unit suite 141/0/0. --- .../ifds/MethodSummaryEdgeApplicationUtils.kt | 15 +++- .../ifds/access/tree/AbstractionExclusions.kt | 18 ++++ .../ap/ifds/access/tree/AccessPath.kt | 8 +- .../ap/ifds/access/tree/AccessTree.kt | 83 ++++++++++++++----- .../ifds/analysis/MethodCallSummaryHandler.kt | 11 ++- .../org/opentaint/dataflow/taint/Cleaner.kt | 25 +++++- .../access/tree/AbstractNodeExclusionTest.kt | 37 +++++++++ .../CleanerFieldSensitivityAnalysisTest.kt | 37 +++------ .../dataflow/DeepCleanSummaryAnalysisTest.kt | 24 ++---- 9 files changed, 180 insertions(+), 78 deletions(-) diff --git a/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/MethodSummaryEdgeApplicationUtils.kt b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/MethodSummaryEdgeApplicationUtils.kt index 65ca456e1..f798abfb2 100644 --- a/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/MethodSummaryEdgeApplicationUtils.kt +++ b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/MethodSummaryEdgeApplicationUtils.kt @@ -6,7 +6,17 @@ import org.opentaint.dataflow.ap.ifds.access.InitialFactAp object MethodSummaryEdgeApplicationUtils { sealed interface SummaryEdgeApplication { data class SummaryApRefinement(val delta: FinalFactAp.Delta) : SummaryEdgeApplication - data class SummaryExclusionRefinement(val exclusion: ExclusionSet) : SummaryEdgeApplication + + /** + * The empty-delta application.

The three tree-only exclusion merge sites (side-effect requirement storage, edge set, summary merging storage) switch from `mergeAndIntersectDeep` to `union`: tree exclusion sets are deep-free now that the starred clean is structural, and `union`'s check turns any leak of a flat deep entry into a loud failure instead of a silent semantics change. The operator itself, the deep accessors on ExclusionSet, and the deep lift in MethodCallSummaryHandler stay: automata and cactus still run the legacy flat channel, the two CommonFactSideEffectSummary sites are shared by all modes, and half-migrating those would change behavior this plan scopes to Task 6.

The tree access-node serializer writes the abstraction's excluded-mark annotation (mask bit 4, then the two depth sets as accessor ids) and reads it back; a round-trip law test pins the sibling shape -- one annotated branch, one plain -- surviving persistence. Persisted method summaries gain a formatVersion property (2), checked on load. Entities written before the property existed read as null and never match -- rejected by version, not silently misread -- and are recomputed. The store-side write stamps the version on both the new-entity and the update paths. Deviation from the plan under its shim clause: the nine "DeepMarkExclusion must not appear in an access path" checks stay, because the flat channel is still live for automata/cactus until Task 6 and the checks guard exactly it.

Concat attachment. filterByAbstraction removed the claimed concrete marks from content attached below an annotated abstract node, but the attachment can itself contain abstract nodes -- there the continuation is not yet known, and the fact can still grow after the attach point's abstraction is consumed. The claim now outlives the attach point on those nodes: the attachment's root inherits the annotation verbatim, everything strictly below it takes each claimed mark from relative depth 1 (collapseToDepth1). Without this, a purely abstract delta -- the demand-refined `arg0.f.*` fact passing through the cleaning callee's summary -- came out unprotected, and the read one statement later re-materialized the cleaned mark: the in-helper clean-then-read false positive. Store partition. propagateAbstractFactWithFieldExcluded rebuilt the surviving abstract remainder of a field write via createAbstractAp(base, exclusions) -- a bare abstract node that drops everything the fact's abstraction carried. The new FinalFactAp.abstractPart() is the dual of removeAbstraction: no concrete children, abstraction kept. Cactus and automata carry the claim on the flat exclusion channel, which both implementations preserve, so their behaviour is unchanged. DeepCleanSummarySample gains the in-helper shapes (clean-then-read, the clean one summary deeper, clean plus a depth-2 constant store on the returned object) with a read-only control; all green on Tree with the control red-less. The two in-helper silent cases and their control are disabled in Automata for the documented intervening-call vacuity, matching CleanerFieldSensitivity. --- .../dataflow/ap/ifds/access/FactAp.kt | 9 +++ .../access/automata/AccessGraphFinalFactAp.kt | 4 ++ .../ap/ifds/access/cactus/AccessCactus.kt | 4 ++ .../ifds/access/tree/AbstractionExclusions.kt | 8 +++ .../ap/ifds/access/tree/AccessTree.kt | 36 +++++++++- .../analysis/JIRMethodSequentFlowFunction.kt | 5 +- .../test/samples/DeepCleanSummarySample.java | 44 ++++++++++++ .../dataflow/DeepCleanSummaryAnalysisTest.kt | 71 ++++++++++++++++++- 8 files changed, 177 insertions(+), 4 deletions(-) diff --git a/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/FactAp.kt b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/FactAp.kt index ac664f773..446974968 100644 --- a/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/FactAp.kt +++ b/core/opentaint-dataflow-core/opentaint-dataflow/src/main/kotlin/org/opentaint/dataflow/ap/ifds/access/FactAp.kt @@ -58,6 +58,15 @@ interface FinalFactAp : FactAp, ReadableAccessorList { fun removeAbstraction(): FinalFactAp? fun abstractOnly(): FinalFactAp + /** + * The dual of [removeAbstraction]: the fact reduced to its root abstraction — no concrete + * children, but everything the abstraction itself carries kept, in particular a starred + * sanitizer's excluded-mark annotation (tree mode).

a starred source assigns both the value and the any-field position; - a starred sanitizer cleans both, keeping the field-clean anchored on the value base; - a starred sink is satisfied by a mark on the value OR on any field. The sink side needs a serialized form of the existing ContainsMarkOnAnyField condition so a rule can express it, added here along with the `withAnyField` position helper.

f5561495461b45f761aaf4e35254b450c7f07eb6 Mon Sep 17 00:00:00 2001 From: Aleksandr Misonizhnik Date: Thu, 23 Jul 2026 18:00:58 +0200 Subject: [PATCH 60/66] feat(go-querylang): star operator parity for Go, and real any-field resolution Parses the starred metavar on plain and typed Go metavars, threads it through the Go taint emitter, and implements the any-field mark check on the Go condition builder. Backs the any-field position with a real resolver on the source, pass and clean paths -- memoized, since any-field evaluation sits on a hot path -- and adds the any-accessor variant of the sanitizer clean on the Go side. Also completes the Java surface: the star threads through assignment-LHS and typed declarations, the any-field shadow tree collapses via an AnyFieldLift decorator, an unsupported starred / pattern-not coincidence is diagnosed rather than silently mis-lowered, and the serialized any-field condition gets its own key so it round-trips independently of the depth-1 mark check. ---

The suffix form was ambiguous with multiplication -- `$X * y` and `$X*y` are ordinary multiplication -- so the prefix spelling is the one the parser can accept unambiguously. Also fixes three clean-path defects the starred sanitizers expose: concrete nested-field taint left behind underneath an any-field position, the sanitizer cleaning only Result instead of its focus position, and the clean not being applied at call-to-start for resolved calls. --- .../dataflow/taint/AnyAccessorCleanTest.kt | 14 ++++- .../GoCallRuleBasedSummaryRewriter.kt | 55 ++++++++++++++++++ .../go/analysis/GoMethodCallFlowFunction.kt | 7 ++- .../grammar/semgrep-extensions.patch | 29 ++++------ .../star_01_sink_field/rule.yaml | 2 +- .../star_01_sink_field/sample.go | 2 +- .../star_02_source_field/rule.yaml | 2 +- .../star_02_source_field/sample.go | 2 +- .../star_03_sanitizer_field/rule.yaml | 2 +- .../star_03_sanitizer_field/sample.go | 6 +- .../xss_07_json_field_write/rule.yaml | 2 +- .../xss_18_template_struct_data/rule.yaml | 2 +- .../samples-go/CmdInjEnvSink/rule.yaml | 8 +-- .../samples-go/CmdTypedReceiverSink/rule.yaml | 4 +- .../samples-go/MapValueToReceiver/rule.yaml | 2 +- .../go/pattern/SemgrepGoPatternParser.kt | 27 ++++++--- .../GoPatternToActionListConverter.kt | 4 +- .../conversion/go/GoTaintRuleGeneration.kt | 8 +-- .../go/GoTaintRuleGenerationCtxExt.kt | 2 +- .../opentaint/semgrep/GoMassiveSampleTest.kt | 2 +- .../semgrep/pattern/GoStarOperatorEmitTest.kt | 14 ++--- .../pattern/SemgrepGoPatternParserTest.kt | 58 +++++++++++-------- .../src/main/java/taint/StarSanitizer.java | 6 +- .../samples/src/main/java/taint/StarSink.java | 2 +- .../src/main/java/taint/StarSource.java | 4 +- .../main/resources/taint/StarSanitizer.yaml | 2 +- .../src/main/resources/taint/StarSink.yaml | 2 +- .../src/main/resources/taint/StarSource.yaml | 2 +- .../src/main/antlr/JavaLexer.g4 | 2 + .../src/main/antlr/JavaParser.g4 | 14 +---- .../pattern/SemgrepJavaPatternParser.kt | 16 +++-- .../pattern/SemgrepRuleLoadErrorMessage.kt | 8 ++- .../automata/MethodFormulaManager.kt | 2 +- .../taint/MethodFormulaSimplifier.kt | 2 +- .../conversion/taint/TaintMarkCheckBuilder.kt | 2 +- .../taint/TaintRegisterAutomataCreation.kt | 2 +- .../taint/TaintRuleGenerationCtx.kt | 2 +- .../conversion/taint/TaintRuleProcessing.kt | 4 +- .../TaintCleanCompositionStrategy.kt | 13 ++++- .../SerializedConditionRoundTripTest.kt | 2 +- .../semgrep/StarOperatorParseTest.kt | 27 ++++----- .../semgrep/StarOperatorRuleGenTest.kt | 18 +++--- .../org/opentaint/semgrep/StarOperatorTest.kt | 2 +- .../semgrep/StarPatternNotCoincidenceTest.kt | 10 ++-- 44 files changed, 245 insertions(+), 153 deletions(-) diff --git a/core/opentaint-dataflow-core/opentaint-dataflow/src/test/kotlin/org/opentaint/dataflow/taint/AnyAccessorCleanTest.kt b/core/opentaint-dataflow-core/opentaint-dataflow/src/test/kotlin/org/opentaint/dataflow/taint/AnyAccessorCleanTest.kt index 97ea52a9f..f63f102ab 100644 --- a/core/opentaint-dataflow-core/opentaint-dataflow/src/test/kotlin/org/opentaint/dataflow/taint/AnyAccessorCleanTest.kt +++ b/core/opentaint-dataflow-core/opentaint-dataflow/src/test/kotlin/org/opentaint/dataflow/taint/AnyAccessorCleanTest.kt @@ -23,7 +23,7 @@ import kotlin.test.assertTrue /** * Characterises the shared [TaintCleanActionEvaluator.removeFinalFact] under an any-accessor position, - * which is what the Go `$VAR*` sanitizer-clean path asks for via `RemoveMark(onAnyAccessor = true)` + * which is what the Go `$*VAR` sanitizer-clean path asks for via `RemoveMark(onAnyAccessor = true)` * (see GoCallRuleBasedSummaryRewriter: `PositionAccess.Complex(base, AnyAccessor)`). * * Whole-object taint is stored as `base.ANY.mark`; a plain base clean uses `Simple(base)`. @@ -76,6 +76,18 @@ class AnyAccessorCleanTest { assertTrue(clean(wholeObject, complexAny).isEmpty(), "any-accessor clean must drop whole-object taint") } + @Test + fun `any-accessor clean removes a concrete nested-field mark`() { + // The whole-object ($*C) sanitizer must clear taint stored on a CONCRETE nested field, + // e.g. base.field.mark, not only the abstract base.ANY.mark.

Replaces the runtime array-element sink reader with an any-field condition, and keeps $X and $*X distinct in the constraint solver. The matrix also pins the remaining whole-object source vs value-sanitizer false positives, so the surviving gaps are characterized rather than silent. --- .../dataflow/taint/AnyAccessorCleanTest.kt |
