A missing authorization vulnerability in Kirby CMS allows authenticated users to bypass intended access restrictions on pages and files, potentially leading to unauthorized information disclosure and content modification; patched in versions 4.9.0 and 5.4.0.

A server-side template injection (SSTI) vulnerability exists in Kirby CMS within the option rendering feature due to double template resolution in option fields (checkboxes, color, multiselect, select, radio, tags, or toggles) when using options from a query or API with untrusted values, potentially allowing attackers to inject malicious queries.
