{"id":"CVE-2026-97176","published":"2026-09-24T06:17:04.227","lastModified":"2026-09-26T23:16:43.073","description":"A flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution. The issue occurs when a client specifically requires a higher security level for a user who already has an active session at a lower level. Due to a logic error in how session re-evaluations are handled, Keycloak may incorrectly issue a token at the lower security level instead of enforcing the required higher level, potentially allowing unauthorized access to sensitive resources that rely on these security claims.","cvssScore":4.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-97176","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539964","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
