🐹gogs.io/gogs

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

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, the endpoint "PUT /repos/:owner/:repo/contents/*" does not require write permissions and allows access with read permission only via repoAssignment(). After passing the permission check, PutContents() invokes UpdateRepoFile(), which results in commit creation and the execution of git push. As a result, a token with read-only permission can be used to modify repository contents. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gogs.io/gogs. 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 gogs.io/gogs to 0.13.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-23632 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 CVE-2026-23632 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 CVE-2026-23632. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
