fix(security): move repo-config.log off predictable /tmp path (CWE-377) - #379
hyperpolymath wants to merge 3 commits into
Conversation
configure-all-repos.sh wrote its audit log to the fixed path
/tmp/repo-config.log. A predictable /tmp path lets another local user
pre-create, symlink, or race the file before this script runs.
LOG_FILE now resolves under the XDG state home
(${XDG_STATE_HOME:-$HOME/.local/state}/personal-sysadmin/repo-config.log),
with the parent directory created mode 0700 before the first write
(split into `mkdir -p` + `chmod 0700` rather than `mkdir -p -m 0700`, to
avoid a new shellcheck SC2174 warning; the leaf directory still ends up
0700). Every `$LOG_FILE` expansion is now double-quoted.
This is a durable operator audit log (bookended "Starting configuration
at ..." / "Configuration complete at ..." messages), not scratch, so it
keeps a stable, re-findable path rather than moving to mktemp -d.
/tmp/repos-to-configure.txt (lines using it are unchanged) is a
durable, shared cache read by 9 sibling scripts in this directory and
is deliberately NOT touched here -- converting it to ephemeral scratch
would break all 9 consumers. Tracked separately:
#377
Verification: bash -n OK; shellcheck clean (matches baseline, only the
pre-existing SC2162 on the `while read repo` loop); grep -nE
"[\"'/]tmp/" shows exactly the 3 untouched repos-to-configure.txt
lines (64, 65, 73), 0 hits on any touched line.

Stop when audit-log setup fails.
The script does not check mkdir, chmod, or the initial tee status. A failure can therefore reach configure_repo, which performs gh api mutations. Check each setup operation and exit before fetching or updating repositories.

What changed and why
configure-all-repos.shwrote its audit log to the fixed path/tmp/repo-config.log. This is CWE-377-class: a predictable/tmppath letsanother local user pre-create, symlink, or race the file before this script
runs.
LOG_FILEnow resolves under the XDG state home:with the parent directory created mode 0700 before the first write. Every
$LOG_FILEexpansion is now double-quoted.Classification: durable log, not scratch. The bookended
"Starting configuration ... at $(date)"/"Configuration complete at $(date)"/"Configured $count repos"messages are an intentional operatoraudit trail, so this keeps a stable, re-findable path rather than moving to
mktemp -d+trap rm(which would delete the log on exit — a functionalregression).
Deliberately not applied here: the coordinator's mid-task correction
adding a
launch-scaffolder/namespace segment to the canonical ladder isscoped to launcher PID/LOG paths. This file is a github-admin audit log,
not a launch-scaffolder-managed launcher — so it stays under
.../personal-sysadmin/repo-config.log, not.../launch-scaffolder/personal-sysadmin/repo-config.log.Deliberately not touched:
/tmp/repos-to-configure.txt(3 occurrences,lines 64/65/73 — unchanged by this PR). It is a durable, shared cache read by
9 sibling scripts in this directory (
add-community-health.sh,add-descriptions.sh,add-justfile-mustfile.sh,add-language-blockers.sh,add-license-badges.sh,add-missing-files.sh,add-readme-roadmap.sh,add-scm-files.sh,advanced-security-config.sh), none of which regenerateit themselves. Converting it to ephemeral scratch would silently break all 9
consumers, so it needs a coordinated fix across all 10 files, out of scope
for this single-file PID/LOG fix. Tracked:
#377
Verification
bash -n— OKshellcheck— clean; only the pre-existing SC2162 (while read repowithout
-r, unrelated to this change) remains, matching baseline exactlygrep -nE "[\"'/]tmp/" configure-all-repos.sh— 0 hits on any touched line;3 hits remain on the deliberately-untouched
repos-to-configure.txtlines(64, 65, 73), named above with a tracking issue
gh api ... -X PATCH/PUT; running it is out of scope and would have real side effects.The log-path change itself (
mkdir -p+chmod 0700, quotedtee/tee -atargets) was verified by inspection and matches the pattern smoke-tested
live in the companion airborne-submarine-squadron and betlang PRs.
