{"id":"PYSEC-2026-1488","summary":"Keylime registrar is vulnerable to Denial-of-Service attack when updated to version 7.12.0","details":"### Impact\nThe Keylime `registrar` implemented more strict type checking on version 7.12.0. As a result, when updated to version 7.12.0, the `registrar` will not accept the format of the data previously stored in the database by versions  \u003e= 7.8.0, raising an exception.\n\nThis makes the Keylime `registrar` vulnerable to a Denial-of-Service attack in an update scenario, as an attacker could populate the `registrar` database by creating multiple valid agent registrations with different UUIDs while the version is still \u003c 7.12.0. Then, when the Keylime `registrar` is updated to the 7.12.0 version, any query to the database matching any of the entries populated by the attacker will result in failure.\n\n### Patches\nUsers should upgrade to versions \u003e= 7.12.1\n\n### Workarounds\n- Remove the registrar database and re-register all agents\n\n### Credit\n\nReported by: Anderson Toshiyuki Sasaki/@ansasaki\nPatched by: Anderson Toshiyuki Sasaki/@ansasaki","aliases":["CVE-2025-1057","GHSA-9jxq-5x44-gx23"],"modified":"2026-07-07T17:47:30.200030852Z","published":"2026-07-07T14:34:49.823034Z","references":[{"type":"WEB","url":"https://github.com/keylime/keylime/security/advisories/GHSA-9jxq-5x44-gx23"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1057"},{"type":"WEB","url":"https://github.com/keylime/keylime/commit/e08b10d86c3717006774e787542c190e2ba24fc7"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2025-1057"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2343894"},{"type":"PACKAGE","url":"https://github.com/keylime/keylime"},{"type":"PACKAGE","url":"https://pypi.org/project/keylime"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-9jxq-5x44-gx23"}],"affected":[{"package":{"name":"keylime","ecosystem":"PyPI","purl":"pkg:pypi/keylime"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.12.0"},{"fixed":"7.12.1"}]}],"versions":["7.12.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/keylime/PYSEC-2026-1488.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L"}]}
