Exploiting CSP in Webkit to Break Authentication & Authorization
WebKit set the documentURI of a CSP violation report to the final cross-origin redirect target instead of the original request URL. A page with a crafted policy could fetch an SSO or OAuth authorize endpoint and read the whole redirect URL, including the authorization code or token, from the violation event, taking over accounts in Safari and every iOS browser.
