Grav is a file-based Web platform. Prior to 1.8.0-beta.27, users with read access on the user account management section of the admin panel can view the password hashes of all users, including the admin user. This exposure can potentially lead to privilege escalation if an attacker can crack these password hashes. This vulnerability is fixed in 1.8.0-beta.27.

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.
