The Image Viewer component in IBM FileNet P8 Application Engine (P8AE) 3.5.1 before 3.5.1-002 removes a user from an ACL when the user is denied all permissions for an annotation, which might allow remote authenticated users to bypass intended access restrictions in opportunistic circumstances.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
