Description

A flaw was found in Spring Boot. A local attacker on the same host as the application may be able to take control of the `ApplicationTemp` directory due to predictable temporary directory handling. When the `server.servlet.session.persistent` setting is enabled and the attack persists across application restarts, this could allow the attacker to read session information, hijack authenticated user sessions, or execute arbitrary code as the application's user.
