they correctly guess the URL, which includes Organisation ID, Client ID, and Client Version of the targeted non-permitted resource. While not trivial to exploit, it could be achieved by brute-forcing or guessing common names. Access to the non-permitted API Keys could allow use of other users' resources without their permission (depending on the specifics of configuration, such as whether an API key is the only form of security). Apiman 3.1.0.Final resolved this issue. Users are advised to upgrade. The only known workaround is to restrict account access.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.
Access supervision ensures privileges are assigned and managed without improper escalation or retention.
Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.
Always invoking the reference monitor prevents missing authorization checks for protected resources.
Requires verification that authorization checks are present and operational for protected resources.
Requiring explicit authorization for each internal connection prevents missing authorization.
Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly.
Manages privileges by authorizing only approved personnel and supervising those lacking required authorizations for maintenance.
