Keycloak 26.7.4: 6 CVEs, Two Unauthenticated DoS
Bottom line: upgrade this week if your login page or SAML endpoints are reachable from the internet, or if you run stateless mode on MySQL/MariaDB. Otherwise take it in your normal cycle. Keycloak 26.7.4 fixes six CVEs — five published as high, one medium. Two of them let an unauthenticated attacker exhaust memory and crash the server by hitting endpoints that are open by definition. One breaking change, in Authorization Services URI matching.
