SCA: security update for concrete5/concrete5 (GHSA-66rg-92q4-6m8q)

low Tenable Self-Hosted Container Security Plugin ID 443905

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Concrete CMS 9.5.0 and below is vulnerable to unauthorized file deletion due to an Inverted CSRF token
check in the DeleteFile controller. The code throws an error when the token IS valid and proceeds with
file deletion when the token is invalid or missing. This effectively disables CSRF protection for the file
deletion endpoint, allowing cross-site request forgery attacks against users who have permission to edit
conversation messages. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 2.3
with a vector of CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Tristan Mandani
for reporting. (CVE-2026-7882)

Update the concrete5/concrete5 library and its related packages to version 9.5.1 or later.
