CVE-2026-30962

Name of the Vulnerable Software and Affected Versions Parse Server versions prior to 9.5.2-alpha.6 Parse Server versions prior to 8.6.19

Description Parse Server, an open source backend deployable on Node.js infrastructures, contains a flaw in its validation process for protected fields. The validation only examines top-level query keys, allowing authenticated users to bypass the protection by embedding query constraints on protected fields within logical operators. This enables unauthorized access and extraction of values from protected fields, as default protected fields exist in all Parse Server deployments.

Recommendations Update to Parse Server version 9.5.2-alpha.6 or later. Update to Parse Server version 8.6.19 or later.
