{"id":"CVE-2026-73197","summary":"Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read","details":"A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.","modified":"2026-09-02T22:10:54.839478649Z","published":"2026-08-20T10:31:31.674Z","related":["CGA-wcwg-375f-x5pw"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73197.json","cna_assigner":"redhat","cwe_ids":["CWE-770"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-73197"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73197.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73197"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2474697"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freeipa/freeipa","events":[{"introduced":"0"},{"fixed":"3af131529c795764b27dca04ce0097db043d355a"}],"database_specific":{"extracted_events":[{"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-2026-73197.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
