CVE-2024-28116
Grav CMS prior to version 1.7.45 is vulnerable to a Server-Side Template Injection (SSTI), which allows any authenticated user (editor permissions are sufficient) to execute arbitrary code on the remote server bypassing the existing security sandbox.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
