The CMCAuthForEST authentication plugin fails open when an EST fullcmc enrollment request is submitted via BasicAuth without an end-user TLS client certificate. The SSL_CLIENT_CERT session attribute retains the EST subsystem's agent certificate, which causes downstream authorization checks to treat the request as agent-privileged. An authenticated EST user can exploit this to obtain CA-signed certificates with arbitrary subject names.","published":"2026-10-02T20:17:01.000Z","lastModified":"2026-10-06T15:09:20.000Z","status":"Awaiting Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-290"],"affected":[],"epss":{"score":0.00204,"percentile":0.1026,"date":"2026-10-26","history":[{"date":"2026-10-03","score":0.00204,"percentile":0.09389}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.20%).
