The current user's role set does not include roles specified in the 'Elevated privilege' field of a UI action, business rule, or script include being executed. (high likelihood)
A scripted REST API endpoint has role-based security configured that the requesting user does not satisfy, either through require_role or manual role checking in the script. (high likelihood)
A business rule with elevated privileges is being triggered by a user action, but the user lacks the admin or security_admin role specified in the rule configuration. (medium likelihood)
Custom scripts are calling gs.hasRole() or similar privilege checking functions with roles the current user does not possess. (medium likelihood)
Access Control List (ACL) rules are denying access to tables or fields required by the operation, causing downstream privilege validation to fail. (low likelihood)
