Grav is a file-based Web platform. Prior to 1.7.53, an authenticated administrator with backup permissions can download a ZIP archive containing the full Grav installation root, including user/accounts/admin.yaml with the administrator password hash and user/config with site configuration, through the backup download endpoint protected only by the session-static admin-nonce URL parameter. This issue is reported as fixed in version 1.7.53.

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.
