Gogs: Stored XSS in branch and wiki views through author and committer names

view advisory published 2026-03-05Licence: CC-BY-4.0

### Summary Stored XSS is still possible through unsafe template rendering that mixes user input with `safe()` plus permissive sanitizer handling of data URLs. ### Details `safe()` still turns off escaping: - internal/template/template.go - `func safe(raw string) template.HTML { return template.HTML(raw) }` Branch pages still render committer names using `safe()`: - templates/repo/branches/overview.tmpl - templates/repo/branches/all.tmpl - templates/repo/wiki/view.tmpl The locale still injects a raw second argument: conf/locale/locale_en-US.ini (`branches.updated_by = updated %[1]s by %[2]s`) ### Impact An attacker who can inject commit metadata such as author/committer name can trigger script execution on affected pages, leading to session abuse, CSRF token theft, or unauthorized actions. ### Recommended Fix - Untrusted arguments should be escaped before being used in translations. - Data URLs should be limited or blocked in the sanitizer. ### Remediation A fix is available at https://github.com/gogs/gogs/releases/tag/v0.14.2.
