This commit disables path-based app sharing by default. It is possible
for a workspace app on a path (not a subdomain) to make API requests to
the Coder API. When accessing your own workspace, this is not much of a
problem. When accessing a shared workspace app, the workspace owner
could include malicious javascript in the page that makes requests to
the Coder API on behalf of the visitor.
This vulnerability does not affect subdomain apps.
- Disables path-based app sharing by default. Previous behavior can be
restored using the `--dangerous-allow-path-app-sharing` flag which is
not recommended.
- Disables users with the site "owner" role from accessing path-based
apps from workspaces they do not own. Previous behavior can be
restored using the `--dangerous-allow-path-app-site-owner-access` flag
which is not recommended.
- Adds a flag `--disable-path-apps` which can be used by
security-conscious admins to disable all path-based apps across the
entire deployment. This check is enforced at app-access time, not at
template-ingest time.
