Test Assertions for Content Security Policy

This page documents the test assertions for the Content Security Policy specification [1].


Comments:

In the CSP Level 2 spec PING ("hyperlink auditing") shows up under form-action[1]. In Fetch it's listed as connect-src[2]. Both Fetch and CSP2 put sendBeacon() under connect-src.


Generic Test Assertions for CSP Level 2

Assertion Test Status
0.1 default-src directive cascades to appropriate policies: script-src, object-src, style-src, img-src, media-src, frame-src, font-src, connect-src bhill
0.2 'self' keyword positive test ryan
0.2.1 'self fails with different scheme TBD
0.2.2 'self' fails with a different port ryan
0.2.3 'self' fails with a different host (including sub-host e.g. foo.com as self with content from bar.foo.com) ryan
0.4 test implicit scheme for a source: succeeds http -> https TBD
0.6 test implicit scheme for a source: fails https -> http TBD
0.7 UNASSIGNED put your idea here - Is there any reliable way to test IPv4 and IPv6 host expressions? TBD
0.8 test wildcard host name matching (e.g. *.foo.com is good, www*.foo.com is bad, *www.foo.com is ???) ryan
0.9 test wildcard port number matching ryan
0.10 test implicit port number and explicit port number matching ryan
0.11 UNASSIGNED - put your test case idea here TBD
0.12 Parsing of source list and policies - semicolons, commas, URL encoded and not, etc. TBD
0.13 Verify that policies enforced for an owning document are also enforced for a Web Worker run by that document TBD
0.14 Verify policy combination logic - multiple policies combine in a least-privilege manner TBD
0.15 Verify policy combination logic - enforced and report-only policies do not interfere with each other TBD
0.16 Verify policy combination logic - multiple policies with different enforcement and different report-uris TBD
0.17 Verify that cross-origin report fetch uses anonymous request, does not accept cookies, headers are appropriately stripped bhill
0.18 Test "dangerous" report-uris - what happens if we use javascript: for reporting? Should only be able to invoke fetch algorithm, not be handled outside the browser. what about ftp:, tel: ? maybe should have to match the scheme the page was loaded over? (what about loading something with file:/// ??) TBD
0.19 Verify that URL restriction rules correctly handle cross-domain redirects. TBD
0.20 What happens with source expression combination: "https: www.webappsec-test.org" applied to an http resource and attempting to load something from http://www.webappsec-test.org/ ?
0.21 Are http://foo.com/ and http://foo.com:80/ same origin?
0.22 Are http://foo.com/ and http://foo.com./ same origin?
0.23 Test 'none' keyword source
0.24 Test 'none' keyword source
0.25 Test 'none' keyword source
0.26 Verify behavior of LINK rel=preload header with CSP Header
0.27 Verify behavior of LINK rel=preload header with CSP meta
0.2 Verify behavior of invalid URL characters in directives, invalid URLs generally
N/A test port matching with non-digits (e.g. octal, hex) - browsers appear not to accept this syntax, so nothing to test
