SCA: security update for parse-server (GHSA-4q3h-vp4r-prv2)

critical Tenable Cloud Security Plugin ID 438025

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 8.6.3 and 9.1.1-alpha.4, an unauthenticated attacker can forge a Google authentication
 token with `alg: "none"` to log in as any user linked to a Google account, without knowing their
 credentials. All deployments with Google authentication enabled are affected. The fix in versions 8.6.3
 and 9.1.1-alpha.4 hardcodes the expected `RS256` algorithm instead of trusting the JWT header, and
 replaces the Google adapter's custom key fetcher with `jwks-rsa` which rejects unknown key IDs. As a
 workaround, dsable Google authentication until upgrading is possible. (CVE-2026-27804)
