As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.<\/p>\n<p>  Severity: 7.4 | HIGH<\/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-2026-46579 Published : May 29, 2026, 9:50 a.m. | 41\u00a0minutes ago Description :A flaw was found in the OpenShift Router.
