NewCVE-2026-30962 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.19, 9.5.2-alpha.6 or higher.
Overview
parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.
Affected versions of this package are vulnerable to Incorrect Authorization in the query validation. An authenticated user can access sensitive field values by wrapping constraints on protected fields inside logical query operators, thereby bypassing intended access restrictions.
Workaround
This vulnerability can be mitigated by using a beforeFind trigger on affected classes to manually inspect queries for protected field references within logical operator sub-queries and reject such requests.
