CVE-2026-97176
mediumA flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution.
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.
