… query This commit fixes a critical SQL injection vulnerability in `internal/storage/sqlite.go` where `sqliteColumnExists` was vulnerable due to the dynamic string interpolation of a table name into a `PRAGMA table_info(%s)` query using `fmt.Sprintf()`. To resolve this issue, the function now safely utilizes SQLite's table-valued function `pragma_table_info(?)`, allowing parameterization and thereby preventing SQL injection. We also added an entry to `.jules/sentinel.md` documenting this finding and learning. Co-authored-by: mattjoyce <278869+mattjoyce@users.noreply.github.com>

-## 2025-02-28 - [CRITICAL] Fix SQL injection in SQLite PRAGMA table_info query +# Sentinel security learnings + +## 2025-02-28 - [CRITICAL] Fix SQL injection in SQLite PRAGMA table_info query + **Vulnerability:** The `sqliteColumnExists` function in `internal/storage/sqlite.go` was vulnerable to SQL injection because it used `fmt.Sprintf` to directly interpolate a table name into a `PRAGMA table_info(%s)` string query. **Learning:** PRAGMA statements cannot accept parameterized inputs natively. If user input reaches this function, an attacker could terminate the string and inject arbitrary SQL. **Prevention:** Instead of string formatting with `PRAGMA table_info`, always use SQLite's table-valued function `pragma_table_info(?)` which safely supports query parameterization (`SELECT ... FROM pragma_table_info(?)`). Note that when doing this, columns like `notnull` must be escaped with double quotes (e.g., `"notnull"`) as they are reserved SQL keywords.🤖 Prompt for AI Agents

🚨 Severity: CRITICAL
💡 Vulnerability: The
sqliteColumnExistsfunction dynamically interpolates thetableargument usingfmt.Sprintfdirectly into aPRAGMA table_info(%s)string query. This risks SQL injection if any user or dynamically generated string input is supplied as the table name.🎯 Impact: This allows an attacker to inject arbitrary SQL logic, bypass security configurations, or alter data if the table input were manipulated.
🔧 Fix: Adopted parameterization through SQLite's built-in
pragma_table_info(?)table-valued function.✅ Verification: Ran
go test -v ./internal/storage/...to verify proper validation without SQL injection risks.PR created automatically by Jules for task 4209861840213903478 started by @mattjoyce
