Summary

On the registration page a user was told to "Remember to check the captcha" while no captcha was on screen. The Turnstile iframe had failed to load (net::ERR_QUIC_PROTOCOL_ERROR on challenges.cloudflare.com), so the widget never rendered, never issued a token and never called onError. Turnstile retried on its own about a minute later and the registration went through, but until then the form was stuck with a prompt the user could not act on. Forgot password, reset password, set password and email verification had the same code and the same failure mode.

While tracing that request in the logs, a second problem showed up: UserService::registerUser logged the whole sign-up payload, including the plaintext password, its confirmation, the Turnstile token and the CSRF token.

Changes

Turnstile on the auth forms

  • New shared TurnstileCaptcha component and useTurnstileCaptcha hook (resources/js/components/turnstile_captcha.js), used by signup, forgot password, reset password, set password and email verification. The five copies of the captcha state are gone.
  • Submitting before a token exists shows "Please wait while we verify you are human, then submit again." instead of "Remember to check the captcha".
  • No token after 15 seconds, or a Turnstile error, shows "We couldn't load the security check…" with a Retry security check button that re-runs the widget. If Turnstile later succeeds on its own, the message clears.
  • An expired or timed-out token re-runs the widget.
  • With no TURNSTILE_SITE_KEY the widget does not render and the client no longer blocks the post. The controllers behind these five forms still require cf-turnstile-response unconditionally, so without a site key the server keeps rejecting the form; this PR does not change that.
  • Each page now exports its component and only mounts when #root exists (same pattern as login.js), so it can be tested.

Registration logging

  • UserService::registerUser now logs the email and the submitted field names only, never the values.

Out of scope

  • The login page has its own variant ("you must check CAPTCHA" after N failed attempts). It will be fixed in a separate PR on top of feat/mfa-phase1, which restructures the login components.

Tests

  • tests/js/components/turnstile_captcha.test.js: captcha states (waiting, token issued, load timeout and retry, error and self-recovery, expiry, no site key).
  • tests/js/turnstile_pages.test.js: the same contract on all five pages (no post before a token, post with a token, retry on error, no widget and no client-side blocking without a site key).
  • tests/UserServiceRegisterLoggingTest.php: registering a user writes neither the password, the Turnstile token nor the CSRF token to the log. Fails on main, passes here.

The Jest config lives on feat/mfa-phase1 (#144) and is not on main yet, so the JS tests run in CI once that lands. Locally:

npx jest tests/js/components/turnstile_captcha.test.js tests/js/turnstile_pages.test.js   # with the jest config from feat/mfa-phase1
docker exec idp-app php vendor/bin/phpunit tests/UserServiceRegisterLoggingTest.php tests/TurnstileProtectedControllersTest.php

Manual check on the local stack with Cloudflare's always-pass test site key and the challenge iframe blocked: register, forgot password and email verification show the failure message and the retry button after 15 seconds; unblocking and pressing retry issues a token and clears the message.

Summary by CodeRabbit

  • New Features
    • Authentication forms now use a consistent CAPTCHA experience, with verification status, timeout handling, and a retry option. Forms wait for successful verification before submitting when CAPTCHA is configured.
  • Bug Fixes
    • Registration logs no longer include submitted credentials or security tokens, helping keep sensitive information out of logs.

When the Turnstile iframe cannot be loaded (e.g. a network error reaching
challenges.cloudflare.com) the widget never renders and onError is not
always invoked. The registration, forgot/reset/set password and email
verification forms then told the user to "check the captcha" while there
was nothing to check.

Move the captcha handling into a shared TurnstileCaptcha component and
useTurnstileCaptcha hook:
- submitting before a token exists asks the user to wait instead
- no token after 15s, or a Turnstile error, shows a failure message with a
  "Retry security check" action that re-runs the widget
- an expired or timed-out token re-runs the widget
- with no site key configured nothing renders and the form is not blocked

Each page now exports its component and only mounts when #root exists so
it can be tested.
UserService::registerUser logged json_encode($payload) at debug level. The
payload is the raw sign-up form, so every registration wrote the plaintext
password, its confirmation, the Turnstile token and the CSRF token to the
application log (prod runs at debug).

Log the email and the submitted field names only.

Walkthrough

Five authentication pages now use a shared Turnstile CAPTCHA hook and component to gate form submission. Registration logging now records the trimmed email and payload field names instead of serialized payload values.

Changes: Turnstile CAPTCHA Flow

Layer / File(s) Summary
Shared CAPTCHA behavior
resources/js/components/turnstile_captcha.js, tests/js/helpers/turnstile_mock.js, tests/js/components/turnstile_captcha.test.js
The shared hook and component manage token checks, verification status, timeout, retry, and widget rendering. Tests cover token issuance, timeout, errors, expiration, retry, and an empty site key.
Authentication page integration
resources/js/email_verification/email_verification.js, resources/js/forgot_password/forgot_password.js, resources/js/reset_password/reset_password.js, resources/js/set_password/set_password.js, resources/js/signup/signup.js, tests/js/turnstile_pages.test.js
The five pages use the shared CAPTCHA flow and stop submission when ensureToken() fails. Each page exports its component and mounts only when #root exists. Parameterized tests cover submission, error and retry UI, and the empty-site-key case.

Registration Logging

Layer / File(s) Summary
Registration log contents
app/Services/Auth/UserService.php, tests/UserServiceRegisterLoggingTest.php
registerUser trims the email before logging and records the email and payload field names instead of serialized payload values. The test checks that the log omits the password and tokens.

Merge Risk: Moderate · previous review c0243

The change adds Turnstile recovery on the auth forms, but its unit tests currently fail in CI. The Retry button may not recover from a script that failed to load, so users behind a blocker could stay stuck. Fix the test setup and the retry behavior before merging.

Assert the registration log content.

The test can pass if the registration log drops the email or field names. Assert both in the registration log line, and use a whitespace-padded email case to exercise trimming.

Review comments at @resources/js/components/turnstile_captcha.js:
- Around line 58-66: Update restart and its use from retry to distinguish an
existing Turnstile widget from a missing one: retain reset for an existing
widget, and when no widget exists, clear the failed script element and restart
script loading through the library’s established mechanism. Ensure retry can
load the script again after a prior load failure; remounting alone is
insufficient.
- Around line 33-42: Update the CAPTCHA load-timeout effect so it stops the
timer when the widget reaches its interactive challenge via onBeforeInteractive,
preventing a usable challenge from being marked failed. Rearm the timer when the
widget restarts, while keeping the existing timeout behavior for loading.

…retry

- An interactive Turnstile challenge can take longer than the 15s load
  timeout. onBeforeInteractive now moves the captcha to an interactive
  state that is not timed out; submitting meanwhile asks the user to
  complete the check. A restart (expiry, challenge timeout) re-arms the
  timeout.
- When api.js itself failed to load (blocked or a network error) there is
  no widget for reset() to act on, and @marsidev/react-turnstile does not
  inject the script again while the failed <script id="cf-turnstile-script">
  is in the DOM. Retry now removes that element and remounts the widget so
  the script is requested again; with the script loaded it still resets
  the widget.
The test listened for MessageLogged and captured nothing in CI, so its
sanity assertion failed although the fix works. Push an in-memory Monolog
TestHandler at debug level onto the logger UserService writes to instead,
so the capture depends neither on the event dispatcher nor on the
channel's configured level, and nothing is written to disk.

…retry

Same change to the shared Turnstile component as in
#184 (444cde1), so both copies stay identical:
an interactive challenge is no longer timed out as a load failure, and
retry reloads api.js when the script itself never loaded.

The login captcha test now simulates a loaded api.js, so retry exercises
the widget reset path.

LGTM only check Copilot's comment

Field names in the sign-up payload are client-controlled, and PHP keeps a
%0A in a form field name as a real newline. They were interpolated into the
log message as plain text, and Laravel's line formatter allows inline line
breaks, so a crafted field name could forge log lines.

JSON-encode the email and the field names in the message. They stay in the
message rather than the context because, with inline line breaks allowed,
Monolog turns escaped newlines in a JSON-encoded context back into real ones.
