{"id":"DEBIAN-CVE-2026-73196","details":"A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service.","modified":"2026-09-14T17:03:31.752508498Z","published":"2026-08-20T11:16:21.417Z","upstream":["CVE-2026-73196"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-73196"}],"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-2026-73196.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-2026-73196.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
