CVE-2024-28119

Summary

CVE-2024-28119 is a vulnerability affecting the open-source content management system, Grav, prior to version 1.7.45. An attacker can exploit the unrestricted access to Twig extension classes from the Grav context to redefine the escape function and execute arbitrary commands. This vulnerability arises due to Twig processing being enabled for static pages, which can be done by any administrative user with the permission to create or edit pages. Since the Twig processor runs unsandboxed, this behavior can lead to arbitrary code execution and privilege escalation on the affected instance. Grav addresses this issue with the release of version 1.7.45, which includes a patch for the vulnerability.
