CVE-2026-39381

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

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
