Weblate: Mercurial argument injection via repository filenames allows authenticated command execution

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.

CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

CWE-88 Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
