CVE-2026-13097high8.7

Ipa: privilege escalation via krbcanonicalname manipulation due to realm-unaware uniqueness enforcement in freeipa ldap datastore

Impact

A privilege escalation flaw in FreeIPA allows a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one, potentially leading to unauthorized acquisition of Kerberos service tickets. The flaw is due to the uniqueness constraint enforced on Kerberos principal name attributes not properly accounting for equivalent representations. Affected versions are not specified.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one. This can lead to unauthorized acquisition of Kerberos service tickets for sensitive services, potentially resulting in full domain compromise.
