Summary

Parse Server's Session Update endpoint allows overwriting server-generated session fields

Details

Impact

An authenticated user can overwrite server-generated session fields such as expiresAt and createdWith when updating their own session via the REST API. This allows bypassing the server's configured session lifetime policy, making a session effectively permanent.

Patches

The fix blocks authenticated users from setting expiresAt and createdWith fields when updating a session. Master key and maintenance key operations are not affected.

Workarounds

There is no known workaround other than upgrading.
