SCA: security update for parse-server (GHSA-mmg8-87c5-jrc2)

medium Tenable Self-Hosted Container Security Plugin ID 439505

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 8.6.70 and 9.7.0-alpha.18, an authenticated user with find class-level permission can
 bypass the protectedFields class-level permission setting on LiveQuery subscriptions. By sending a
 subscription with a $or, $and, or $nor operator value as a plain object with numeric keys and a length
 property (an "array-like" object) instead of an array, the protected-field guard is bypassed. The
 subscription event firing acts as a binary oracle, allowing the attacker to infer whether a protected
 field matches a given test value. This issue has been patched in versions 8.6.70 and 9.7.0-alpha.18.
 (CVE-2026-34595)

Solution

Update the parse-server library and its related packages to version 8.6.70 or later.
