What is CVE-2026-72819?

Grav CMS versions prior to 2.0.13 are susceptible to a remote code execution vulnerability due to improper validation in the Flex Objects plugin settings. Authenticated users can exploit this flaw by uploading a ZIP archive containing malicious PHP code. By leveraging array notation to bypass normal name validation, attackers can invoke the 'unZip' function and deploy harmful PHP files to the server's web root, leading to potential unauthorized code execution.
