详情介绍:

Cloudflare Access can put a login in front of /wp-admin and /wp-login.php. It only helps if every request really passes through Cloudflare. Without Cloudflare Tunnel, anyone who knows the origin's address can reach WordPress directly and skip Access entirely. DIESIS JWT Auth for Cloudflare Access closes that gap. For the paths you choose, WordPress itself checks the Cf-Access-Jwt-Assertion header that Cloudflare Access adds to authenticated requests. A request without a valid token is answered with HTTP 403 before WordPress does anything else. What it does What it does not do Safe defaults Enforcement only runs when the settings are complete and the issuer is an HTTPS cloudflareaccess.com URL. Incomplete or invalid settings disable enforcement instead of locking you out. If Cloudflare's key endpoint is temporarily unreachable, a previously cached key set keeps working. Third-party service To verify tokens the plugin downloads the public signing keys of your Cloudflare Access team from the issuer you configure, for example https://your-team.cloudflareaccess.com/cdn-cgi/access/certs. No site data is sent; the request is a plain download of public keys, repeated at most every 12 hours or after a key rotation. Cloudflare's terms and privacy policy apply to that endpoint: Terms, Privacy policy. Source code, issues and support: github.com/DiesisMedia/diesis-jwt-auth

安装:

  1. Create a self-hosted application in Cloudflare Zero Trust that covers your WordPress login and admin paths, and note the team domain (the issuer) and the application audience tag.
  2. Install the plugin from the WordPress plugin directory or upload the ZIP under Plugins > Add New Plugin > Upload Plugin, then activate it.
  3. Open Settings > DIESIS JWT Auth.
  4. Enter the issuer, for example https://your-team.cloudflareaccess.com, and the application audience. Save with enforcement still disabled.
  5. Check that the protected paths match the paths your Access application covers. Use the copyable defaults below, adjusting the prefix if WordPress is installed in a subdirectory.
  6. Enable enforcement and save.
  7. Test twice: once through your Cloudflare URL, which should work, and once directly against the origin, which should return 403.
Default settings A fresh installation starts with these values: Copy these lines into Protected paths, one per line, for WordPress installed at the domain root: /wp-login.php /wp-admin /wp-admin/ If your login and admin URLs start with /wordpress/, use: /wordpress/wp-login.php /wordpress/wp-admin /wordpress/wp-admin/ Use the path prefix from your actual login and admin URLs, without the domain. Leaving Protected paths empty restores the default three paths; it does not disable protection. Issuer and Application audience are specific to your Cloudflare setup and have no shared default. Leave Allowed emails and Excluded paths empty for the default setup. If you add an email allowlist, use your actual permitted addresses, one per line, matching your Access policy.

升级注意事项:

1.4.1 Adds a review request in the admin. No settings change needed. 1.4.0 The plugin UI follows the WordPress language. No settings change needed. 1.3.0 Plugin slug renamed to diesis-jwt-auth. Installs of the earlier diesis-wp-jwt-auth folder are separate plugins: install this one, enter or copy the settings, then delete the old folder. 1.2.0 Plugin renamed. Settings and behaviour are unchanged; no action needed.

常见问题:

I excluded a path in WordPress, but Cloudflare still asks me to log in.

Exclusions in this plugin only stop the origin check. Cloudflare Access decides on its own which paths it intercepts. Leave the path public in the Access application as well.

Why does a request get a 403?

Any failed check ends in 403: no Cf-Access-Jwt-Assertion header, a token not signed with RS256, an invalid or expired signature, a wrong issuer or audience, a missing email claim, or an email that is not on the allowed list. With WP_DEBUG enabled the reason is written to the PHP error log.

I locked myself out. How do I get back in?

Make sure you are opening the site through Cloudflare, not through the origin's own address, and that the Access application covers the same paths as the plugin. If you need to disable the plugin without admin access, rename or delete its folder under wp-content/plugins/ via SFTP or your host's file manager.

What happens when Cloudflare's certificate endpoint is down?

A cached key set stays valid for 12 hours and keeps working. Only if there are no cached keys at all and Cloudflare cannot be reached are protected requests denied.

Does the plugin work with Cloudflare Access service tokens?

No. Service tokens carry a common_name instead of an email and are always denied. Keep paths used by machines out of the protected paths.

How do I get rid of the review notice?

Follow the review link: that ends it for your account for good. "Remind me later" brings the notice back after three months, after a year and after two years; the last reminder offers "Don't show this again" instead and ends it as well. The notice only ever appears on the Dashboard, the Plugins screen and the plugin's own settings page, and only once enforcement has been running for two weeks.

Does it work on multisite?

Yes. Settings are per site, and uninstalling cleans up every site of the network.
