CVE-2026-32742 Details
Description
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.17 and 8.6.42, an authenticated user can overwrite server-generated session fields (`sessionToken`, `expiresAt`, `createdWith`) when creating a session object via `POST /classes/_Session`. This allows bypassing the server's session expiration policy by setting an arbitrary far-future expiration date. It also allows setting a predictable session token value. Starting in version 9.6.0-alpha.17 and 8.6.42, the session creation endpoint filters out server-generated fields from user-supplied data, preventing them from being overwritten. As a workaround, add a `beforeSave` trigger on the `_Session` class to validate and reject or strip any user-supplied values for `sessionToken`, `expiresAt`, and `createdWith`.
A vulnerability exists in Parse Server versions 9.0.0 prior to 9.6.0-alpha.17 and 8.6.42 prior to 8.6.42, allowing authenticated users to overwrite server-generated session fields, including 'sessionToken', 'expiresAt', and 'createdWith', when creating a session object via 'POST /classes/_Session'. This exploitation can bypass the server's session expiration policy by setting an arbitrary far-future expiration date and allows for the insertion of a predictable session token value.
Users can upgrade to Parse Server versions 9.6.0-alpha.17 or 8.6.42, where this vulnerability has been patched. Alternatively, a 'beforeSave' trigger can be added on the '_Session' class to validate and reject or strip any user-supplied values for 'sessionToken', 'expiresAt', and 'createdWith'.
