Name of the Vulnerable Software and Affected Versions Parse Server versions prior to 8.6.57 Parse Server versions prior to 9.6.0-alpha.48

Description An authenticated user can modify server-generated session fields, such as expiresAt and createdWith, when updating their own session through the REST API. This bypasses the server’s session lifetime policy, potentially making a session permanent. The issue affects the ability to manage session duration, allowing for extended or indefinite session access.
