Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Bitnami packages — download data is not available via public APIs for these ecosystems.

Description

Gitea's stopwatch API does not re-validate repository access permissions. After a user's access to a private repository is revoked, they may still view issue titles and repository names through previously started stopwatches.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gitea, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update gitea to 1.25.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-644v-xv3j-xgqg is resolved across your whole dependency graph.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-644v-xv3j-xgqg can be triaged on real exposure rather than presence alone.

Tailored to GHSA-644v-xv3j-xgqg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
