**Name of the Vulnerable Software and Affected Versions** Khoj versions prior to 1.29.10 **Description** The issue is related to an Insecure Direct Object Reference (IDOR) vulnerability in the update subscription endpoint, allowing any authenticated user to manipulate other users' Stripe subscriptions by modifying the `email` parameter in the request. The vulnerability exists in the subscription endpoint at "/api/subscription", which uses an `email` parameter as a direct reference to user subscriptions without verifying object ownership. While authentication is required, there is no authorization check to verify if the authenticated user owns the referenced subscription. **Recommendations** For versions prior to 1.29.10, update to version 1.29.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the `/api/subscription` endpoint to prevent unauthorized subscription modifications. Additionally, avoid using the `email` parameter in the affected API endpoint until the issue is resolved.
