Technical details

A path traversal and symlink following vulnerability exists in Weblate's ZIP download functionality. The application fails to properly validate files before inclusion in the generated ZIP archive, allowing it to follow symbolic links that point to locations outside the intended repository directory. An authenticated attacker with network access can exploit this to read arbitrary files from the host filesystem. The vulnerability is addressed in version 5.17.
