Summary
Weblate is a web based localization tool. Prior to version 5.6.2, Weblate didn't correctly validate filenames when restoring project backup. It may be possible to gain unauthorized access to files on the server using a crafted ZIP file. This issue has been addressed in Weblate 5.6.2. As a workaround, do not allow untrusted users to create projects.

Fencer Intel 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.
