Description

AI Translation Available

Weblate is a web-based continuous localization platform used to manage software translations. Weblate 4.11.1 through 2026.7.1 contains an argument-injection vulnerability in its Mercurial backend. Repository filenames beginning with - could be interpreted as Mercurial options instead of literal paths. An authenticated user with project-scoped component.edit permission could exploit this through a Mercurial-backed RESX component using the Update RESX files add-on. A later repository update could execute arbitrary commands with the privileges of the Weblate service account. This is a residual incomplete fix for CVE-2022-23915. This issue has been patched in version 2026.8.
