The handler had a stale inline heredoc that used a '{{ csrf }}' string
substitution to inject the token. The home.php template created in Task 2
is the canonical version (uses render_layout + Escape::attr). Switching
to the template removes the duplicated markup and the ad-hoc str_replace
escape path.
PostTeamEditor interpolated the scenario id into a <script> block as
'localStorage.setItem("scenario:<id>", ...)', so an id containing
'</script><script>...</script>' would break out of the JS-string context
and execute in the browser. Use json_encode with JSON_HEX_TAG / HEX_AMP /
HEX_APOS / HEX_QUOT so the id is always a safe JS string literal.
Adds a PostTeamEditorTest case that submits '</script><script>alert(1)</script>'
and asserts the literal '<script>alert(1)</script>' substring is absent
from the response. Updates the existing happy-path and FullFlowTest
assertions to match the new 'scenario:"demo"' (quoted) form.
- ImageUploadService::store() now returns /assets/uploads/<token>/<file>
so the URL the upload handler emits matches the new GET route.
- public/index.php registers a dedicated GET /assets/uploads/{userToken}/{filename}
route; the legacy /assets/{kind}/{filename} is kept as a fallback.
- GetAssets reads the upload token from $request->server['__uploads_token']
(the front controller threads it that way) instead of the cookies bag.
- Adds GetAssets unit tests for the upload-token happy path and a
token-mismatch 404, plus a FullFlowTest step that uploads and re-fetches
the asset through the front controller.
