Summary

Kirby is an open-source content management system. Prior to 4.9.4 and 5.4.4, Kirby sites using the pages field with roles that have the pages.access permission disabled allowed authenticated users to provide an inaccessible parent page or site to the page picker backend and confirm arbitrary page existence and retrieve title field values. This issue is fixed in versions 4.9.4 and 5.4.4.

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.
