CVE-2026-34574 · Parse Server: Session field immutability bypass via falsy-value guard
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.69 and 9.7.0-alpha.14, an authenticated user can bypass the immutability guard on session fields (expiresAt, createdWith) by sending a null value in a PUT request to the session update endpoint. This allows nullifying the session expiry, making the session valid indefinitely and bypassing configured session length policies. This issue has been patched in versions 8.6.69 and 9.7.0-alpha.14.
