CVE-2026-104988 – Pki-core: dogtag-pki: redhat-pki: pki: est fullcmc authentication bypass allows certificate mis-issuance with arbitrary subject

​CVE ID :CVE-2026-104988

Published : Oct. 2, 2026, 8:17 p.m. | 1 hour, 11 minutes ago

Description :A flaw was found in Dogtag PKI (pki-core). 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.

Severity: 8.1 | HIGH
