CVE-2026-41654 (opens in a new tab)How to fix?
Upgrade weblate to version 5.17.1 or higher.
Overview
weblate is an A web-based continuous localization system with tight version control integration
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through the ProjectBackup restore path in the backup import code. An attacker can supply a crafted project backup with component repo or push URLs that point to internal or non-public addresses, causing the restore process to contact attacker-chosen network targets. This can expose internal services reachable from the Weblate host and let an attacker use the restore workflow to probe or access protected network resources.
Workarounds
- Limit who can create projects (
project.addpermission), so fewer users can import crafted project backups and trigger the SSRF path.
