critical Tenable Cloud Security Plugin ID 438604

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 9.5.2-alpha.8 and 8.6.21, a vulnerability in Parse Server's query handling allows an
authenticated or unauthenticated attacker to exfiltrate session tokens of other users by exploiting the
redirectClassNameForKey query parameter. Exfiltrated session tokens can be used to take over user
accounts. The vulnerability requires the attacker to be able to create or update an object with a new
relation field, which depends on the Class-Level Permissions of at least one class. This vulnerability is
fixed in 9.5.2-alpha.8 and 8.6.21. (CVE-2026-30965)

Solution

Update the parse-server library and its related packages to version 8.6.21 or later.
