CVE-2024-52294

描述

### Summary An Insecure Direct Object Reference (IDOR) vulnerability in the update_subscription endpoint allows any authenticated user to manipulate other users' Stripe subscriptions by simply modifying the email parameter in the request. ### Details The vulnerability exists in the subscription endpoint at `/api/subscription`. The endpoint 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. Vulnerable code in `/api/subscription`: ```python @subscription_router.patch("") @requires(["authenticated"]) async def update_subscription(request: Request, email: str, operation: str): # IDOR: email parameter directly references user subscriptions without ownership verification customers = stripe.Customer.list(email=email).auto_paging_iter() customer = next(customers, None) if operation == "cancel": # Any authenticated user can modify any subscription referenced by email customer_id = customer.id for subscription in stripe.Subscription.list(customer=customer_id): stripe.Subscription.modify(subscription.id, cancel_at_period_end=True) ``` ### PoC 1. Create a customer account in stripe: - Customer A: `adventure8812@zeropath.com` (attacker) 2. Log in as any user. 3. Send this request: ```http PATCH /api/subscription?email=adventure8812@zeropath.com&operation=cancel HTTP/1.1 ``` 4. The subscription for Customer A is successfully set to cancel. ### Impact High: Revenue loss via mass cancellation of subscriptions. Loss of customer trust by re-enabling subscriptions they had set to cancel. ### Resolution This was fixed in the following commit which limited subscription update operations to the authenticated user: https://github.com/khoj-ai/khoj/commit/47d3c8c23597900af708bdc60aced3ae5d2064c1. Support for arbitrarily presenting an email for update has been deprecated.
