CVE-2023-47837Network attack vector

Subscriber-level membership-plan bypass

Published Jun 4, 2024 · Updated Apr 28, 2026

Improper privilege management in Repute InfoSystems ARMember 4.0.10 and earlier allows remote authenticated users to bypass membership plans. Published records state that the plugin fails to restrict access to membership levels, but they do not identify the affected function, request parameter, or unchecked key. Subscriber-level access is required; successful exploitation grants membership-level access outside the subscriber's assigned plan.
