FreeScout: Keep administrators to the proxy - #996
Requires administrators to use the helpdesk through the proxy. Agents are still allowed in from anywhere, since most of them don't have proxy access.
How it works
The signal comes from nginx. It sets a WPORG_PROXIED_REQUEST FastCGI param to 1 for the proxy's IP addresses and 0 for everyone else, the same check WPORG_PROXIED_REQUEST makes on WordPress.org. The proxy IP list stays with Systems instead of being copied into the module.
Enforcement is in RequireWordPressOrgLogin. When WPORG_SSO_REQUIRE_PROXY=true, an administrator's request without the param set to 1 ends their session. They're sent to the login page with an error, and polls get a 401. This applies however they logged in, break-glass included, so a stolen admin session doesn't work from outside the proxy.
A missing param fails closed. If nginx doesn't pass the param, nobody counts as proxied, and an error is logged once an hour. WPORG_SSO_REQUIRE_PROXY=false lets administrators back in.
Behavior is unchanged until the variable is set. It defaults to false.
Deploying
Systems add the geo map and the fastcgi_param on the FreeScout VM (example in Modules/WPOrgSSO/README.md). The map needs the proxy's IPv6 addresses as well as IPv4.
Set WPORG_SSO_REQUIRE_PROXY=true.
Testing
npm run freescout:test (from environments/). The new ProxyTest covers:
proxied administrators staying logged in;
logging out administrators who are unproxied, missing the param, or only sending a spoofed header;
Administrators can be required to access the app through a configured proxy, regardless of how they signed in. Requests without the expected proxy marker log administrators out; API polling requests receive a 401 response. Agents are unaffected.
Proxy enforcement is optional and disabled by default. Requests are not considered proxied if the required marker is missing or appears only in a request header.
Documentation
Added setup guidance for enabling proxy enforcement and configuring nginx to mark proxied requests.
WPOrgSSO adds an optional proxy requirement for administrator access. When enabled, middleware logs out administrators whose requests lack the nginx proxy marker. The change adds configuration, provider checks, logout responses, deployment instructions, and tests.

Summary
Proxy configuration and request marker freescout.wordpress.net/Modules/WPOrgSSO/Config/config.php, freescout.wordpress.net/Modules/WPOrgSSO/Providers/WPOrgSSOServiceProvider.php, freescout.wordpress.net/Modules/WPOrgSSO/README.md, freescout.wordpress.net/README.md, freescout.wordpress.net/Modules/WPOrgSSO/module.json
Adds the require_proxy setting, defaulting to false. The provider checks whether the nginx server variable equals '1' and logs a configuration error at most once per 60 seconds when the variable is absent. The documentation describes the setting and nginx configuration. The module version changes from 1.0.3 to 1.0.4.
When proxy enforcement is enabled, the middleware logs out administrators whose requests are not marked as proxied. It invalidates the session and returns a JSON 401 or redirects to login. Tests cover proxied and non-proxied requests, missing markers, header handling, agents, and disabled enforcement.

Merge Risk: Low · previous review c6a40
Administrators using password login may be logged out without seeing why. The change is mergeable with this bounded usability issue acknowledged or fixed.
Security architecture risk: Low · up to 26be9
The application adds a fail-closed control for administrator web requests, including sessions created through emergency login. No introduced bypass was established. Successful deployment still depends on trustworthy proxy classification, and coverage of privileged endpoints outside the web middleware remains unconfirmed.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The affected authorization scope is administrator web access to this helpdesk. An incorrect infrastructure classification could admit requests carrying administrator authority or deny all administrators; agent access deliberately remains unchanged. A broader cross-service privilege expansion was not established.
Security Findings and Attack Paths
observed — The reviewed application path does not accept a same-named client header as the proxy marker, and rejects missing markers. Tests represent these cases and an unproxied existing administrator session. These controls counter a direct header-spoofing bypass but do not verify deployed nginx address classification.
Trust Boundaries and Controls
observed — nginx owns origin classification, while WPOrgSSO trusts the resulting FastCGI value and combines it with authenticated administrator identity. Enforcement is registered on the web group; the SAML ACS and metadata routes remain in an open, throttled group. Production forwarding trust and privileged non-web route coverage remain unresolved.
Resilience and Maintainability Implications
inferred — Repeated covered requests cannot rely solely on an earlier successful login: each authenticated administrator request rechecks proxy status. Rejecting one request terminates its dispatch and invalidates its session. This does not establish cancellation of already-running requests or enforcement for independently authenticated non-web endpoints.
Hardening Proposals
proposed — Before activation, validate the deployed trusted-address configuration with proxied, unproxied, spoofed-forwarding-header, IPv4 and IPv6 requests. Confirm that privileged core and private-module endpoints receive this policy or an equivalent control, and preserve an infrastructure-level recovery path for administrator lockout.

- Line 122: Update the proxy-check flow around log_out so the proxy error is
displayed on the password login view when enforced() is false; use a public hook
supported by that view, while preserving the existing logout behavior.

With WPORG_SSO_REQUIRE_PROXY=true, WPOrgSSO logs administrators out of any
request that nginx doesn't mark as proxied with the WPORG_PROXIED_REQUEST
FastCGI param, however they logged in. A session stolen from an administrator
then doesn't work from outside the proxy. Agents aren't affected.

Until WordPress.org is enforced, the login page is core's password form,
which doesn't show the module's session error, so administrators logged
out from outside the proxy weren't told why. Show it through core's
login_form.before action.
Bumps WPOrgSSO to 1.2.0, past trunk's 1.1.0.
