Subject: fix: crash loading non-standard schemes in iframes
|
|
|
|
This fixes a crash that occurs when loading non-standard schemes from
|
|
iframes or webviews. This was happening because
|
|
ChildProcessSecurityPolicyImpl::CanAccessDataForOrigin contains explicit
|
|
exceptions to allow built-in non-standard schemes, but does not check
|
|
for non-standard schemes registered by the embedder.
|
|
|
|
This patch adjusts the origin calculation for subframe non-standard schemes in
|
|
- browser process at `NavigationRequest::GetOriginForURLLoaderFactoryUncheckedWithDebugInfo`
|
|
- render process at `DocumentLoader::CalculateOrigin`
|
|
|
|
When top level frame navigates to non-standard scheme url, the origin is calculated
|
|
as `null` without any derivation. It is only in cases where there is a `initiator_origin`
|
|
then the origin is derived from it, which is usually the case for renderer initiated
|
|
navigations and iframes are no exceptions from this rule.
|
|
|
|
The patch should be removed in favor of either:
|
|
- Remove support for non-standard custom schemes
|
|
- Register non-standard custom schemes as websafe schemes and update
|
|
CPSPI::CanAccessDataForOrigin to allow them for any navigation.
|
|
- Update the callsite to use RFHI::CanCommitOriginAndUrl in upstream, previous
|
|
effort to do this can be found at https://chromium-review.googlesource.com/c/chromium/src/+/3856266.
