Summary
Parse Server before versions 8.6.69 and 9.7.0-alpha.14 allows an authenticated user to bypass the immutability guard on session fields (expiresAt, createdWith) by sending a null value in a PUT request to the session update endpoint. This allows nullifying the session expiry, making the session valid indefinitely and bypassing configured session length policies.
Risk Assessment
The organization is at risk of unlimited session duration, potentially leading to unauthorized data access and violation of session security policies.
Recommendation
Immediately upgrade Parse Server to version 8.6.69 or 9.7.0-alpha.14, which contain the fix.
