GHSA-j8xr-c56q-m8jj

Fix: go-gitea/gitea#36340

GHSA-j8xr-c56q-m8jj is a CWE-284 vulnerability in github.com/go-gitea/gitea. O3 Security confirms whether GHSA-j8xr-c56q-m8jj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Gitea improperly exposes issue titles and repository names through previously started stopwatches

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go 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 github.com/go-gitea/gitea. 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.

  2. Fix

    Update github.com/go-gitea/gitea to 1.25.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j8xr-c56q-m8jj 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 pinpoints whether GHSA-j8xr-c56q-m8jj 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-j8xr-c56q-m8jj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
