An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript.

This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods.<\/p>\n<p>  Severity: 4.3 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-8830 Published : May 19, 2026, 6:04 a.m. | 56\u00a0minutes ago Description :A flaw was found in Keycloak.
