Summary
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 enforce proper access control. This issue has been fixed in version 5.17. If users are unable to update immediately, they can work around this issue by blocking access to /api/memory/ in the HTTP server, which removes access to this feature.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
