CVE-2026-34244
MEDIUM5.0EPSS 0.01%Weblate: SSRF via Project-Level Machinery Configuration
Description
### 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. ### References Thanks to @DavidCarliez for disclosing this via GitHub private vulnerability reporting.
