GHSA-hgr3-x44x-33hx

Fix: go-gitea/gitea#36320

GHSA-hgr3-x44x-33hx is a CWE-284 vulnerability in code.gitea.io/gitea. O3 Security confirms whether GHSA-hgr3-x44x-33hx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Gitea has improper access control for uploaded attachments

Real-World Exposure

1 pkg affected
🐹code.gitea.io/gitea

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 does not properly verify repository context when deleting attachments. A user who previously uploaded an attachment to a repository may be able to delete it after losing access to that repository by making the request through a different repository they can access.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for code.gitea.io/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 code.gitea.io/gitea to 1.25.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hgr3-x44x-33hx 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-hgr3-x44x-33hx 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-hgr3-x44x-33hx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
