CVE-2026-34244 Details
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.
A Server-Side Request Forgery (SSRF) vulnerability has been identified in Weblate, a web-based localization tool, affecting versions prior to 5.17. Users with the 'project.edit' permission can configure machine translation service URLs that point to arbitrary internal network addresses. During the validation of these configurations, Weblate sends an HTTP request to the specified URL and reflects up to 200 characters of the response back to the user in an error message. This vulnerability allows for partial response reading from the attacked URL.
Weblate has released a patch for this vulnerability in version 5.17. Users can upgrade to this version to address the issue. If an immediate upgrade is not possible, the WEBLATE_MACHINERY setting can be used to limit available machinery services and mitigate the vulnerability.
