Bug ID: 204375
Summary: Fix Timing-Allow-Origin check in ResourceTiming
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: New Bugs
Assignee: webkit-unassigned at lists.webkit.org
Reporter: npm at chromium.org
In https://github.com/web-platform-tests/wpt/pull/20320 I added a test to check the behavior landing in https://github.com/whatwg/fetch/pull/955. Essentially there are two changes:
Same-origin check is replaced with 'response tainting' from Fetch.
When Fetch's 'tainted origin flag' is set, having a TAO header equal to the request origin is not a valid way to pass the TAO check (instead, requires '*' or 'null').
Use https://wpt.fyi/results/resource-timing/crossorigin-sandwich-TAO.sub.html?label=master&label=experimental to know whether this passes on Safari (probably doesn't but hasn't loaded the test yet).
