{"id":"CVE-2026-19550","summary":"Freeipa: ipa: freeipa: trust-fetch-domains uses trust-read aci to gate a privileged ad trust refresh, allowing unauthorized ldap writes","details":"A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied server and credentials, resulting in unauthorized, attacker-controlled modification of trusted-domain and ID-range identity data in the IPA LDAP directory.","modified":"2026-11-05T21:15:38.496172265Z","published":"2026-08-11T20:46:42.019Z","related":["ALSA-2026:70564","ALSA-2026:72279","ALSA-2026:83460"],"database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/19xxx/CVE-2026-19550.json","unresolved_ranges":[{"extracted_events":[{"strategy":"InverseAffectedRanges","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":"8040020261027121250.f153676a"},{"fixed":"8040020261027121355.5b01ab7e"},{"fixed":"8040020261027121250.f153676a"},{"fixed":"8040020261027121355.5b01ab7e"},{"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"}]}],"cna_assigner":"redhat"},"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/errata/RHSA-2026:93452"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-19550"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/19xxx/CVE-2026-19550.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-19550"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514019"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freeipa/freeipa","events":[{"introduced":"0"},{"fixed":"3af131529c795764b27dca04ce0097db043d355a"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"4.13.3"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:freeipa:freeipa:*:*:*:*:*:*:*:*"}]}}],"versions":["release-4-13-2","release-4-13-1","release-4-13-0","rc_4-9-0-1","release-4-8-0","rc_4-8-0-1","rc_4-7-0-2","rc_4-7-0-1","release-4-4-1","release-4-4-0","alpha_1-4-4-0","release-4-2-0","alpha_1-4-2-0","release-4-0-0","release-3-3-0","beta_2-3-3-0","beta_1-3-3-0","release-3-2-0","beta_1-3-2-0","release-3-2-0-pre1","release-3-1-0","beta_2-3-0-0","beta_1-3-0-0","release-2-1-0","release-2-0-0","rc_3-2-0-0","rc_2-2-0-0","rc_1-2-0-0","beta_1-2-0-0","alpha_5-1-9-0-1","alpha_5-1-9-0","alpha_4-1-9-0","alpha_3-1-9-0","alpha_2-1-9-0","alpha-1-9-0","release-1-1-0","release-1-0-0","milestone_6","milestone_4_1","milestone_4","milestone_3","milestone_2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-19550.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
