Bugs

• P0 - CSP 1.0 turned on for Firefox OS - https://bugzilla.mozilla.org/show_bug.cgi?id=858787 (assign=grobinson)
  • grobinson has spent some time on this and discovered some other blocking bugs that he has fixed or is fixing

• P1 - (CSP 1.0) CSP should not block inline scripts or eval unless script-src or default-src are included - https://bugzilla.mozilla.org/show_bug.cgi?id=885433 (assign=grobinson)
• P2 - (CSP 1.0) report destination loosening - https://bugzilla.mozilla.org/show_bug.cgi?id=843311 - helps adoption but isn't crucial
• P2 - (CSP 1.0) EventSource needs to be restricted using connect-src directive https://bugzilla.mozilla.org/show_bug.cgi?id=802872
  • needs to be tested to make sure it isn't already
• P2 - (CSP 1.0) Verify that content added by XSLT stylesheet is subject to document's CSP - https://bugzilla.mozilla.org/show_bug.cgi?id=663567
  • needs someone to test it
• P2 - redirects / nsIContentPolicy - test cases involving redirects fail for some reason
• P2 - (CSP 1.1) - script-nonce (helps with adoption) - land behind a pref, grobinson has written a patch for this
• P2 - improve error messages/logging - https://bugzilla.mozilla.org/show_bug.cgi?id=607067 https://bugzilla.mozilla.org/show_bug.cgi?id=792161
• P3 (spec unclear?) Content Security Policy (CSP) blocks SVG embedded as data URI in CSS url() (affects b2g) https://bugzilla.mozilla.org/show_bug.cgi?id=878608
• P3 - fix bookmarklets to work with CSP - https://bugzilla.mozilla.org/show_bug.cgi?id=866522
• P3 - (CSP 1.1) https://bugzilla.mozilla.org/show_bug.cgi?id=826805 - allow HTTPS content when an http source is present (in 1.1 spec)
• P3 - (CSP 1.1) meta support - many issues to resolve - https://bugzilla.mozilla.org/show_bug.cgi?id=663570
• P3 - (CSP 1.1) paths - https://bugzilla.mozilla.org/show_bug.cgi?id=808292
• P3 - C++ rewrite
• P3 - sandbox (depends on iframe sandbox work that isn't complete (needs allow-popups, bug 785310) - https://bugzilla.mozilla.org/show_bug.cgi?id=671389
• P4 (not in spec) block CSSOM calls without style-src: unsafe-eval https://bugzilla.mozilla.org/show_bug.cgi?id=873302 - needs proposal and discussion on the WG list
• P4 - (CSP 1.0) eval bypass using crypto.generateCRMFRequest https://bugzilla.mozilla.org/show_bug.cgi?id=824652 - can already run script in this case
• P4 (spec under development still) - frame options https://bugzilla.mozilla.org/show_bug.cgi?id=846978 (have existing frame-ancestors, going to fix X-Frame-Options - https://bugzilla.mozilla.org/show_bug.cgi?id=725490)

Things To Do ?

• script-nonce / script-hash (CSP 1.1)
• paths (CSP 1.1)
• sandbox (options 1.0, in csp1.1)
• anything else from CSP 1.1 or UI Safety specs ?
• frame-options (pretty much == frame-ancestors)
• redirects / general nsIContentPolicy issue ?

ACTIONS

• figure out if W3C test suite failures are legit - file bugs for the failures that are
  • Brad Hill test suite: http://webappsec-test.info/web-platform-tests/CSP/
• needs confirmation - Verify that content added by XSLT stylesheet is subject to document's CSP - https://bugzilla.mozilla.org/show_bug.cgi?id=663567
• needs confirmation - EventSource needs to be restricted using connect-src directive https://bugzilla.mozilla.org/show_bug.cgi?id=802872 - test to make sure it isn't already
