### Impact A user with the `project.edit` permission (granted by the per-project "Administration" role) can configure machine translation service URLs pointing to arbitrary internal network addresses. During configuration validation, Weblate makes an HTTP request to the attacker-controlled URL and reflects up to 200 characters of the response body back to the user in an error message. This constitutes a Server-Side Request Forgery (SSRF) with partial response read.

### Patches

* https://github.com/WeblateOrg/weblate/pull/18684 * The solution then has been cleaned up in followup patches

### Workarounds Limiting available machinery services via WEBLATE_MACHINERY setting can avoid this.
