AI-analyzed exploit summary This repository contains an auto-generated stub module for CVE-2026-53902, an authorization bypass vulnerability in MCO's /customer/servlet/mco/webapi/profile-sections/group-membership endpoint. The code includes placeholder logic for probing the target but lacks actual exploit implementation.

MCO does not properly enforce authorization checks in the /customer/servlet/mco/webapi/profile-sections/group-membership endpoint. An authenticated user can modify their group membership without proper authorization checks, allowing privilege escalation. An attacker can add themselves to arbitrary groups by supplying a valid group ID, which can be obtained via other application functionalities (e.g. /customer/servlet/mco/webapi/group/picker/groups), provided he has necessary permissions, or potentially inferred through brute-force techniques. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
