Affected: Atlassian Crowd Data Center, Atlassian Crowd Server, atlassian crowd

Affected versions of Atlassian Crowd allow an attacker to authenticate as the crowd application via security misconfiguration and subsequent ability to call privileged endpoints in Crowd's REST API under the {{usermanagement}} path.

This vulnerability can only be exploited by IPs specified under the crowd application allowlist in the Remote Addresses configuration, which is {{none}} by default.

The affected versions are all versions 3.x.x, versions 4.x.x before version 4.4.4, and versions 5.x.x before 5.0.3
