Walkthrough

Nginx configurations add security headers to Docker Compose routes and CORS headers to OIDC discovery routes. The OIDC UI configurations remove the OpenID Credential Issuer proxy route and its endpoint from the Helm values list.

Changes

Proxy Header Configuration

Layer / File(s) Summary
Docker Compose route headers
docker-compose/nginx.conf
The /v1/esignet and root routes add security headers. The OpenID configuration, JWKS, and OAuth authorization-server routes add security headers, CORS settings, and response type mappings.
OIDC UI metadata CORS
oidc-ui/nginx/nginx.conf, helm/oidc-ui/templates/configmap.yaml, helm/oidc-ui/values.yaml
The discovery routes add CORS settings. The Nginx configuration maps the listed extensions to text/plain. The OpenID Credential Issuer proxy route and its entry in DEFAULT_WELLKNOWN are removed.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to e5cbe

Browser requests for discovery metadata may fail across these deployments because responses contain duplicate CORS origin headers. Keep one owner for that header before merging.

Architecture Summary

Architecture risk: 🔵 Low · up to e5cbe

The change affects 3 systems.

Changed systems: helm, docker-compose, oidc-ui

Architecture concerns
No architecture-level concerns identified.

Before / after behavior

  • observed — Modified behavior in docker-compose/nginx.conf: A blank line was added after the error log directive; no configuration behavior changed.
  • observed — Modified behavior in docker-compose/nginx.conf: The /v1/esignet route now adds a default-deny Content-Security-Policy and a no-referrer policy to responses.
  • observed — Modified behavior in docker-compose/nginx.conf: The OpenID configuration route now adds default-deny CSP and no-referrer headers, allows CORS for GET and OPTIONS with the listed request headers, and declares text/plain, log, cer, json, and txt response types.
  • observed — Modified behavior in docker-compose/nginx.conf: The JWKS route now adds default-deny CSP and no-referrer headers, allows CORS for GET and OPTIONS with the listed request headers, and declares text/plain, log, cer, json, and txt response types.

@zesu22, I checked all three nginx configurations in PR #2001. The /.well-known/openid-credential-issuer location is still present in docker-compose/nginx.conf at Line 82, oidc-ui/nginx/nginx.conf at Line 83, and the nginx.conf embedded in helm/oidc-ui/templates/configmap.yaml at Line 100.

To address @anushasunkada’s request, remove that location block from all three configurations. Leave the other /.well-known/ locations unchanged.

Suppress the upstream CORS header before adding the Nginx header.

Each discovery location adds Access-Control-Allow-Origin: *, and the proxied Spring handlers also return the same header through @CrossOrigin(origins = "*"). Without proxy_hide_header, Nginx can send duplicate Access-Control-Allow-Origin fields, which browsers can reject. Suppress the upstream field in all three locations or remove the Nginx header layer.

Prevent duplicate CORS origin headers in both Nginx configurations.

All three backend metadata handlers use @CrossOrigin(origins = "*"). Nginx forwards their origin header and now adds another one. Browsers reject cross-origin responses with duplicate origin headers. Keep one CORS owner per route; if Nginx must set the header, hide the upstream header in every affected location. (docs.spring.io)

  • oidc-ui/nginx/nginx.conf#L44-L44: Hide the upstream origin header in the OpenID configuration location.
  • oidc-ui/nginx/nginx.conf#L60-L60: Hide the upstream origin header in the JWKS location.
  • oidc-ui/nginx/nginx.conf#L76-L76: Hide the upstream origin header in the authorization-server location.
  • helm/oidc-ui/templates/configmap.yaml#L58-L58: Hide the upstream origin header in the JWKS location.
  • helm/oidc-ui/templates/configmap.yaml#L75-L75: Hide the upstream origin header in the OpenID configuration location.
  • helm/oidc-ui/templates/configmap.yaml#L92-L92: Hide the upstream origin header in the authorization-server location.
Apply this directive to each listed location
 location /.well-known/openid-configuration {
+  proxy_hide_header Access-Control-Allow-Origin;
   proxy_pass         http://esignet.esignet/v1/esignet/oidc/.well-known/openid-configuration;

Use the corresponding indentation and existing proxy_pass value in helm/oidc-ui/templates/configmap.yaml.
