CVE-2026-39381: Parse Server's Endpoint `/sessions/me` bypasses `_Session` `protectedFields`

April 8, 2026 (updated April 15, 2026)

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.
