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 upload a crafted SVG file as the issue attachment to archive XSS. All installations allow uploading SVG (text/xml) files as issue attachments (non-default) are affected.

Patches

Correctly setting the Content Security Policy for the serving endpoint. Users should upgrade to 0.12.7 or the latest 0.13.0+dev.

Workarounds

Disable uploading SVG files (text/xml) as issue attachments.

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 0.12.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ff28-f46g-r9g8 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
