Executive Summary

This vulnerability occurs because after a user logs out, the JSON Web Token (JWT) used for authentication is not invalidated. This means that if an attacker steals or intercepts the token, they can reuse it freely until it expires, which by default is 2 hours but can be changed.

Impact Analysis

An attacker who obtains a valid JWT can continue to access the system as the authenticated user until the token expires, potentially leading to unauthorized access and misuse of the user's privileges.

Mitigation Strategies

Upgrade Payload to version 3.44.0 or later, where the issue has been fixed. Until then, consider reducing the JWT expiration time to minimize the window of token reuse and monitor for suspicious token reuse activity.
