Description
CVE-2026-41654 is a medium severity vulnerability in Weblate versions prior to 5.17.1. It allows an authenticated user with project.add permission to import a crafted project backup ZIP containing a component JSON with a malicious repository URL. This URL can point to private network addresses or use disallowed schemes, bypassing input validation due to the use of bulk_create which skips Django's full_clean validation. The malicious URL is then written directly into the . git/config file. This issue has been fixed in Weblate version 5.17.
