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 before 1.8.0 allows 1FA for user accounts that have completed 2FA enrollment. If a user's credentials are known, then an attacker could send them to the API without requiring the 2FA one-time password.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update code.gitea.io/gitea to 1.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-11576 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Frequently Asked Questions

Gitea before 1.8.0 allows 1FA for user accounts that have completed 2FA enrollment. If a user's credentials are known, then an attacker could send them to the API without requiring the 2FA one-time password.
