Bludit Session Invalidation Bypass After User Deletion

Bludit is a content management system. Versions prior to 3.22.0 have a Broken Access Control flaw where active sessions remain valid even after the corresponding user account has been physically deleted from the database. This "Ghost Session" allows revoked users to maintain full unauthorized access to the system. Version 3.22.0 fixes the issue.

Casky was already ahead

This CVE exploits attack patterns that Casky's 261matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

Bludit CMS versions before 3.22.0 contain a critical broken access control vulnerability where user sessions persist in active state even after the user account is deleted from the database. This "Ghost Session" flaw allows revoked or terminated users to maintain full unauthorized access to the content management system, potentially enabling data exfiltration, unauthorized content modification, or further lateral movement. Organizations running vulnerable Bludit instances face significant risk, particularly those managing sensitive content or multi-user environments where employee offboarding processes depend on account deletion for access revocation.

Casky's 261 matched skills leverage Claude's extended reasoning to detect attack patterns associated with TA0004 (Privilege Escalation) and TA0006 (Credential Access) techniques by analyzing session lifecycle behaviors, authentication state inconsistencies, and database integrity gaps. Practitioners using Casky would observe findings related to CWE-285 (Improper Authorization) and CWE-613 (Insufficient Session Expiration) through detection of orphaned sessions—active authentication tokens belonging to non-existent user accounts, continued API calls from revoked credentials, and unauthorized state modifications occurring after deletion events. The platform's skills would flag anomalies in session validation logic and recommend immediate session invalidation routines upon user deletion, helping teams identify both the vulnerability footprint and active exploitation attempts in their Bludit deployments.
