What is CVE-2026-34244?
CVE-2026-34244 is a medium-severity server-side request forgery vulnerability in WeblateOrg weblate, published on 15 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Weblate is a web based localization tool. In versions prior to 5.17, 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. This issue has been fixed in version 5.17. If developers are unable to immediately upgrade, they can limit available machinery services via WEBLATE_MACHINERY setting.
