The routes that start a single sign-on and hand out a passkey sign-in challenge are reached without authentication and stored pending state in bounded tables that dropped their oldest entry when full, whoever had started it. An attacker who starts sign-ins a few times a second (about a hundred a second for passkeys) pushes every other user&#39;s pending sign-in out of the table before that user&#39;s browser returns, denying single sign-on and passkey sign-in for as long as the requests continue.</p> <p><strong>Affected:</strong> Progressive Robot Ltd hMailServer</p> <p>Uncontrolled eviction in the pending sign-in tables of the REST API in Progressive Robot hMailServer 6.3.4 and 6.3.5 allows a remote unauthenticated attacker to make other users&#39; OpenID Connect, SAML and passkey sign-ins fail.
