{"id":"DEBIAN-CVE-2026-13097","details":"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.","modified":"2026-09-24T08:47:28.522814224Z","published":"2026-08-20T11:16:20.293Z","upstream":["CVE-2026-13097"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-13097"}],"affected":[{"package":{"name":"freeipa","ecosystem":"Debian:12","purl":"pkg:deb/debian/freeipa?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.10.1+dfsg1-1+exp1","4.10.1-1+exp1","4.10.2-1","4.10.2-2","4.10.2-2+exp1","4.11.1-1","4.11.1-1+exp1","4.11.1-2","4.11.1-2+exp1","4.11.1-2.1","4.12.2-1","4.12.2-2","4.12.2-3","4.12.4-1","4.12.4-2","4.13.1-1","4.9.11-1","4.9.11-1+exp1","4.9.11-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13097.json"}},{"package":{"name":"freeipa","ecosystem":"Debian:13","purl":"pkg:deb/debian/freeipa?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.4-1","4.12.4-2","4.13.1-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13097.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N"}]}
