Vulnerability Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.8.0-alpha.7 and 8.6.75, the GET /sessions/me endpoint returns _Session fields that the server operator explicitly configured as protected via the protectedFields server option. Any authenticated user can retrieve their own session's protected fields with a single request. The equivalent GET /sessions and GET /sessions/:objectId endpoints correctly strip protected fields. This vulnerability is fixed in 9.8.0-alpha.7 and 8.6.75.
