TIMELINE

Sep 23 PATCH SHIPPED — CVE-2026-76578 (Red Hat Enterprise Linux 9). Fixed in Red Hat Enterprise Linux 9 0:4.13.4-1.el9_8.
Description
A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.
