| Title | Psi Probe <=5.3.0 Broken Access Control |
|---|
| Description | Psi Probe versions up to and including 5.3.0 allow any authenticated user with the "probeuser" role to terminate multiple user sessions simultaneously through the /app/expire_list.htm endpoint. The application processes bulk session expiration requests without validating ownership of the target sessions, enabling low-privileged users to cause widespread denial of service by forcibly logging out multiple users across different web applications in a single HTTP request.
