Detailsinfo A vulnerability was found in parse-community parse-server up to 8.6.41/9.6.0-alpha.16. It has been rated as problematic. This issue affects an unknown code block of the component Session Creation Endpoint. The manipulation with an unknown input leads to a dynamically-determined object attributes vulnerability. Using CWE to declare the problem leads to CWE-915. The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. Impacted is integrity. The summary by CVE is: 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`. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-32742 since 03/13/2026. The exploitation is known to be easy. The attack may be initiated remotely. Neither technical details nor an exploit are publicly available. Upgrading to version 8.6.42 or 9.6.0-alpha.17 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
