Parameter Value
CVSS 5.3 (MEDIUM)
Affected Versions 9.0.0 — 9.8.0
Fixed In 9.8.0
Type CWE-863 (Incorrect Authorization)
Vendor Parseplatform
Public PoC No

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.
