Vulnerability from cvelistv5 – Published: 2026-07-24 15:12 – Updated: 2026-07-24 15:12

Title

Pki-core: dogtag-pki: redhat-pki: pki-core: ca renewal request processing omits realm authorization check performed by enrollment path

Summary

A flaw was found in pki-core. The certificate authority (CA) renewal request path does not perform the realm-based authorization check that the enrollment path performs, allowing an authenticated user entitled to one realm to cause a certificate belonging to a different realm to be renewed without that realm's authorization.

Severity

3.1 (Low)

For deployments that do use realm-based authorization, using a renewal profile that additionally restricts renewal requests to the original requester narrows exposure: the shipped caDirUserRenewal.cfg profile configures authz.acl=user_origreq=\"auth_token.uid\", which independently blocks cross-user renewal by comparing the renewing caller\u0027s UID against the UID that submitted the original request. This is a partial mitigation only -- it is realm-blind rather than realm-aware, so a UID collision across two independently-administered realms\u0027 user directories would still bypass it -- and it does not apply to caManualRenewal.cfg or other shipped renewal profiles that configure no authz.acl, which remain exploitable as described. No complete mitigation is available; apply the update once released."
