Keycloak 26.7.3 Released: 20 CVEs, No Fix for 26.4–26.6
Bottom line: not an emergency, but upgrade this week if you use token exchange with a Google or Microsoft broker, or FGAP v2 to delegate admin rights. On 26.4, 26.5 or 26.6 there is no patch for you today. Keycloak 26.7.3 fixes 20 CVEs — one high, 17 medium, one low, one unrated — plus two breaking changes. Every one needs a delegated admin account, client credentials, or an intercepted authorization code; the single high is in a test-only dependency.
