The issue occurs when the silent authentication path prompt=none is used, which allows the authorization process to skip certain steps if a user is already logged in. Due to this bypass, the security rule that ensures a pushed request URI is used only once is not enforced. An attacker could potentially reuse a request URI to obtain multiple authorization codes for a user who is already signed in, violating security standards like FAPI-2.","epss":{"date":"2026-11-05","percentile":0.19694,"score":0.00272},"exploits":[],"kev":null,"metrics":[{"score":4.2,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},{"score":4.2,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793963842637,"publishedAt":1790161430346,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-96446"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539284"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-96446"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539284"}],"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":"d48a3c25cf854b131cdb194b79fd56ce4bc448ce753f964adefabff0be99adf3","sources":[{"modifiedAt":1793960837984,"name":"CNA: redhat","retrievedAt":1793963483554,"url":"https://www.cve.org/CVERecord?id=CVE-2026-96446"},{"modifiedAt":1793963842637,"name":"NVD","retrievedAt":1793967460605,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96446"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793963498474,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96446"}],"ssvc":{"assessedAt":1790462714542,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Keycloak-services: keycloak-services: par single-use bypass via prompt=none silent authentication path","updatedAt":1793967460605}
