NewCVE-2026-30965 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.21, 9.5.2-alpha.8 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 redirectClassNameForKey query parameter handling. An unauthenticated attacker can gain unauthorized access to session tokens of other users by crafting requests that exploit insufficient access control checks after query redirection.
Workaround
This vulnerability can be mitigated by setting restrictive Class-Level Permissions to prevent clients from creating new fields on classes, specifically by disabling addField for public access and unauthenticated users.
