FreeIPA Flaw Chain Lets Anonymous Clients Create Reusable Administrator Credentials
Summary: Red Hat says a chain of two flaws lets a client that has never logged in create a Kerberos identity of its own choosing in FreeIPA and end up in the administrators group, reproduced twice on a default installation and tracked as CVE-2026-76578 with a preliminary CVSS score of 9.8. The chain depends on a 389 Directory Server ownership rule that compares an empty client name to an empty stored value, scored 7.5 as CVE-2026-76560, and FreeIPA fixed its side in version 4.13.4.
Key Takeaway: An untouched FreeIPA install ships the exact default rule shape the chain needs, and Red Hat reproduced it against the stock 4.13.1 container image using administrator-only commands to confirm the result. Neither the advisories nor the bug reports publish detection rules or indicators, and neither project says whether a fix removes an identity an attacker created beforehand or what an administrator should look for.
