CVE-2026-63302

Quick.CMS is vulnerable to Local File Inclusion (LFI) in the admin.php endpoint via the p parameter. An authenticated attacker with admin privileges can include arbitrary files located within the application's directory structure via a crafted HTTP request. Successful exploitation allows disclosure of the server's directory structure and absolute file paths (path disclosure). The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
