Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-269.

Summary

OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, so anonymous attackers can set restricted attributes such as group membership. Attackers can register through the legacy self-service REST endpoint or the User Self-Service flow to join administrative groups and gain full administrative control of OpenAM. The flaw is classified as CWE-269.
