Detailsinfo

A vulnerability was found in Roskus Prospero Flow CRM up to 5.5.0. It has been rated as problematic. This issue affects the function DeleteNotificationController::delete of the file /notification/delete of the component Notification. The manipulation of the argument id with an unknown input leads to a resource injection vulnerability. Using CWE to declare the problem leads to CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. Impacted is integrity, and availability. The summary by CVE is:

The vulnerability involves an Insecure Direct Object Reference (IDOR) in the `DeleteNotificationController::delete()` method at endpoint `GET /notification/delete/{id}`. The flaw allows any authenticated user, regardless of company or permissions, to delete notifications belonging to any other user in the system. The controller retrieves the target record with `Notification::findOrFail($id)` and deletes it without validating `user_id` or `company_id` ownership, unlike the sibling `SetNotificationReadAjaxController`, which correctly scopes lookups by `Auth::id()`. Because notification identifiers are sequential, an attacker can iterate over IDs to systematically delete notifications belonging to any user, denying them visibility of ticket alerts, task assignments, and other system events.
