Gogs through 0.13.0 allows argument injection during the previewing of changes.

GHSA-9pp6-wq8c-3w2c — Gogs allows argument injection during the previewing of changes

Affected: Go: gogs.io/gogs

### Impact

Unprivileged user accounts can write to arbitrary files on the filesystem. We could demonstrate its exploitation to force a re-installation of the instance, granting administrator rights. It allows accessing and altering any user's code hosted on the same instance.

### Patches

Unintended Git options has been ignored for diff preview (https://github.com/gogs/gogs/pull/7871). Users should upgrade to 0.13.1 or the latest 0.14.0+dev.

### Workarounds

No viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions.

WID-SEC-W-2026-2013 — Gogs: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen in Gogs ausnutzen, um erweiterte Berechtigungen zu erlangen, beliebigen Code auszuführen – sogar mit erweiterten Berechtigungen, was zur vollständigen Kontrolle über das System führen kann –, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, Cross-Site-Scripting-Angriffe durchzuführen, Benutzer auf bösartige Websites umzuleiten oder einen Denial-of-Service-Zustand zu verursachen.
