CVE-2026-33220

Weblate: JavaScript localization CDN add-on allows arbitrary local file read outside the repository

State: Published
Severity: 6.8 Medium

Description

Weblate is a web based localization tool. In versions prior to 5.17, the translation memory API exposed unintended endpoints, which in turn didn't perform proper access control. This issue has been fixed in version 5.17. If developers are unable to update immediately, they can disable this feature as the CDN add-on is not enabled by default.
