Lifecycle Timeline
4Description
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.
Analysis
Parse Server versions prior to 9.8.0-alpha.7 and 8.6.75 expose protected session fields to authenticated users via the GET /sessions/me endpoint, bypassing the protectedFields server configuration that should restrict access to sensitive data. An authenticated attacker can retrieve their own session's protected fields in a single request, whereas the equivalent GET /sessions and GET /sessions/:objectId endpoints correctly enforce field-level access controls. …
