Description
A vulnerability was determined in yoanbernabeu grepai up to 0.35.0. The affected element is the function PostgresStore.LookupByContentHash of the file indexer/chunker.go of the component Postgres Embedding Cache. Executing a manipulation of the argument content_hash can lead to use of weak hash. The attack needs to be launched locally. The attack requires a high level of complexity. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. The pull request to fix this issue awaits acceptance.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/yoanbernabeu/grepai. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/yoanbernabeu/grepai has shipped for GHSA-q76h-p6jh-9rw3 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-q76h-p6jh-9rw3 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-q76h-p6jh-9rw3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
