CVE-2026-7879
Concrete CMS has an unauthorized file access issue
EPSS 0.22%
Description
In Concrete CMS 9.5.0 and below, the submit_password() method in concrete/controllers/single_page/download_file.php allows unauthorized file access since downloading permission-restricted files bypasses the view_file permission check. Files without passwords can be downloaded and any user who knows a file's password can download a password protected file regardless of whether they have permission to access the file. The Concrete CMS security team thanks Youssef Eid for reporting this issue.
