Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.12 and 8.6.38, an unauthenticated attacker can take over any user account that was created with an authentication provider that does not validate the format of the user identifier (e.g. anonymous authentication). By sending a crafted login request, the attacker can cause the server to perform a pattern-matching query instead of an exact-match lookup, allowing the attacker to match an existing user and obtain a valid session token for that user's account. Both MongoDB and PostgreSQL database backends are affected. Any Parse Server deployment that allows anonymous authentication (enabled by default) is vulnerable. This vulnerability is fixed in 9.6.0-alpha.12 and 8.6.38.

RemediationAI
Within 24 hours: Audit all Parse Server deployments to identify instances with anonymous authentication enabled and document exposure scope; disable anonymous authentication if not operationally required. Within 7 days: Implement compensating controls (WAF rules to block pattern-matching queries, network segmentation limiting Parse Server access, enhanced logging/monitoring for suspicious authentication attempts). …
