SCA: security update for parse-server (GHSA-fph2-r4qg-9576)

high Tenable Cloud Security Plugin ID 439078

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
 Prior to versions 8.6.53 and 9.6.0-alpha.42, Parse Server's LiveQuery WebSocket interface does not enforce
 Class-Level Permission (CLP) pointer permissions (readUserFields and pointerFields). Any authenticated
 user can subscribe to LiveQuery events and receive real-time updates for all objects in classes protected
 by pointer permissions, regardless of whether the pointer fields on those objects point to the subscribing
 user. This bypasses the intended read access control, allowing unauthorized access to potentially
 sensitive data that is correctly restricted via the REST API. This issue has been patched in versions
 8.6.53 and 9.6.0-alpha.42. (CVE-2026-33421)

Solution

Update the parse-server library and its related packages to version 8.6.53 or later.
