## Description

An access control vulnerability in Nagios Network Analyzer 2024R1.0.3 allows deleted users to retain access to system resources due to improper session invalidation and stale token handling. When an administrator deletes a user account, the backend fails to terminate active sessions and revoke associated API tokens, enabling unauthorized access to restricted functions.
