CyberRota Analysis
AI-GeneratedConcrete CMS versions prior to 9.5.3 are vulnerable due to a lack of checks on user account status and email validation during the OAuth callback login process. This oversight allows deactivated or unvalidated users to authenticate and establish a fully authenticated session, potentially leading to unauthorized access. Organizations using affected versions should prioritize remediation to prevent exploitation of this medium-severity vulnerability.
Original NVD Description
Concrete CMS OAuth callback login path prior to version 9.5.3 did not check whether an account was active or email-validated before establishing a session. A deactivated or unvalidated user with an existing OAuth binding could complete authentication and receive a session that was fully authenticated for the callback response, with the login recorded and login events dispatched. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 6.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N.
