Real-World Exposure

1 pkg affected
🐹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

Impact

The malicious user is able to discover services in the internal network through repository migration functionality. All installations accepting public traffic are affected.

Patches

Internal network CIDRs are prohibited to be used as repository migration targets. Users should upgrade to 0.12.5 or the latest 0.13.0+dev.

Workarounds

Run Gogs in its own private network.

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

  2. Fix

    Update gogs.io/gogs to 0.12.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q347-cg56-pcq4 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.
