Technical details
The plugin fails to honour the configured criterion for linking incoming SSO identities to WordPress accounts, always resolving by login name regardless of configuration. An attacker controlling the identity provider can assert arbitrary login names to authenticate as any user without ownership verification. This is an authentication bypass allowing unauthenticated privilege escalation when the attacker has IdP control.
