The issue occurs when the server parses XML documents containing excessively long dateTime or duration values. Because these strings are not properly validated before processing, the XML parser consumes excessive CPU time. An unauthenticated remote attacker can exploit this by sending specially crafted SAML requests to the server, leading to high CPU utilization and a denial of service for all users.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793912027046,"publishedAt":1793894687688,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-107123"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2547297"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability."}],"revision":"6ba40a7b0b7573a986b2fe237a249d8c685eea7dd2810d08de224613371d6941","sources":[{"modifiedAt":1793912027046,"name":"CNA: redhat","retrievedAt":1793913731279,"url":"https://www.cve.org/CVERecord?id=CVE-2026-107123"}],"ssvc":{"assessedAt":1793912019682,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Keycloak-services: keycloak-services: unauthenticated cpu denial of service via saml xml datetime and duration parsing","updatedAt":1793913731279}
