CSP Strict-Dynamic Shifts Script Trust From Hosts to Execution Lineage

CSP Strict-Dynamic Shifts Script Trust From Hosts to Execution Lineage A page can carry a restrictive script host list and still face a difficult deployment choice when its trusted bootstrap code loads dependencies at runtime. Adding every current script host to script-src keeps policy tied to network locations that can change. Adding 'strict-dynamic' takes a different route: in supporting browsers, trust attached to a nonce-bearing or hash-authorized root script can propagate to scripts that root code inserts dynamically.
