{"id":"CVE-2026-13097","summary":"Ipa: privilege escalation via krbcanonicalname manipulation due to realm-unaware uniqueness enforcement in freeipa ldap datastore","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":"2026-10-31T02:47:39.655905307Z","published":"2026-08-20T10:37:55.464Z","related":["ALSA-2026:70564","ALSA-2026:72279","ALSA-2026:83460"],"database_specific":{"cna_assigner":"redhat","cwe_ids":["CWE-706"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13097.json","unresolved_ranges":[{"extracted_events":[{"range":[{"fixed":"0:4.13.4-1.el10_2"},{"fixed":"0:4.12.2-15.el10_0.7"},{"fixed":"0:4.6.8-5.el7_9.25"},{"fixed":"8100020261007071200.143e9e98"},{"fixed":"8100020261007070536.823393f5"},{"fixed":"8060020261008134123.c1533a64"},{"fixed":"8060020261008133528.ada582f1"},{"fixed":"8060020261008134123.c1533a64"},{"fixed":"8060020261008133528.ada582f1"},{"fixed":"8080020261007080925.e581a9e4"},{"fixed":"8080020261007071832.b0a6ceea"},{"fixed":"8080020261007080925.e581a9e4"},{"fixed":"8080020261007071832.b0a6ceea"},{"fixed":"0:4.13.4-1.el9_8"},{"fixed":"0:4.10.1-12.el9_2.7"},{"fixed":"0:4.11.0-15.el9_4.9"},{"fixed":"0:4.12.2-14.el9_6.8"}],"source":"AFFECTED_FIELD","strategy":"InverseAffectedRanges"}]}]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:70564"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:72279"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:82935"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:83083"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:83084"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:83085"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:83460"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:83461"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:89836"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:93071"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-13097"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13097.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13097"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2515974"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freeipa/freeipa","events":[{"introduced":"c7da7e0dc979c2ecd834a0727114f53cdf878297"},{"last_affected":"c7da7e0dc979c2ecd834a0727114f53cdf878297"}],"database_specific":{"extracted_events":[{"cpe":"cpe:2.3:a:freeipa:freeipa:4.12.2:*:*:*:*:*:*:*","range":[{"introduced":"4.12.2"},{"last_affected":"4.12.2"}],"source":"CPE_STRING"}]}}],"versions":["4.12.2","release-4-12-2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-13097.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N"}]}
