Gogs is an open source self-hosted Git service. Prior to 0.14.3, a malicious user with rights to create a new file on a repository or wiki page can trigger a denial of service condition in which the pages containing the listing of files will return HTTP error 500 and render the web interface unusable for the repository or wiki. The issue is present in file internal/route/repo/wiki.go and internal/route/repo/view.go where the pages try to recover commit information. If errors are returned while recovering commit information, the page will return a 500 error and stop rendering, resulting in a denial of service. This vulnerability is fixed in 0.14.3.

GHSA-3qq3-668m-v9mj — Gogs has a Denial of Service in repository/wiki file listing web pages

2026-10-03T16:55:18.575835+00:00

Affected: Go: gogs.io/gogs

### Summary A malicious user with rights to create a new file on a repository or wiki page can trigger a denial of service condition in which the pages containing the listing of files will return HTTP error 500 and render the web interface unusable for the repository or wiki.

### Details The issue is present in file `internal/route/repo/wiki.go` and `internal/route/repo/view.go` where the pages try to recover commit information. If errors are returned while recovering commit information, the page will return a 500 error and stop rendering, resulting in a denial of service. In `view.go` the issue occurs at [line 56](https://github.com/gogs/gogs/blob/89f0f86c7e1a3be7f48d99e27818a79d17357558/internal/route/repo/view.go#L56) while a slightly different issue occurs in `wiki.go` at [line 174](https://github.com/gogs/gogs/blob/89f0f86c7e1a3be7f48d99e27818a79d17357558/internal/route/repo/wiki.go#L174) where `commits[0]` is dereferenced without checking if it contains value. It is possible to trigger issues in assigning the correct value to variable `commits` by using a specific string as part of the page title. The issue is linked to the fact that file names can contain special characters such as `*`, `?`, `[`, `]`, etc. that will be interpreted as git's pathspec instead of a simple string. So crafting a name containing an incomplete pathspec sequence will trigger this error.

### PoC As a proof of concept consider the file name `"[]` and how it affects repository and wiki pages.…

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

2026-10-03T16:55:18.575889+00:00

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.
