307-310: LGTM! Consider adding security documentation.The change to allow 'localhost' as a valid redirect URL is necessary for Electron's OpenID authentication flow. However, it would be beneficial to document this security exception with a comment explaining why it's necessary and safe in this context.
Add a comment above the condition:
+ // Allow localhost for Electron app's OpenID authentication if ( redirectUrl.hostname === serverUrl.hostname || redirectUrl.hostname === 'localhost' ) {

307-310: Verify security implications and OpenID flows.
While the change is necessary for Electron, let's verify:
- That this doesn't affect other OpenID authentication flows
- That the security implications are acceptable
✅ Verification successful
Let me gather more specific information about the OpenID implementation and URL validation.
Let me get the complete implementation of the URL validation and the server hostname retrieval to fully understand the security checks.
The URL validation is secure and OpenID flows are properly implemented
The implementation is secure because:
- The
isValidRedirectUrlfunction properly validates URLs against the configured OpenID server hostname - It only allows redirects to either the same hostname as the OpenID server or localhost
- The OpenID callback flow uses standard security measures:
- Code verifier for PKCE
- State parameter validation
- ID token validation
- Proper redirect URI configuration
The change to allow localhost redirects is acceptable for Electron apps and doesn't compromise security as:
- It's a standard practice for desktop applications
- The validation still ensures redirects can only go to localhost or the authorized server
- Other OpenID flows remain unaffected as they continue using the server hostname validation

Since Electron window can't go to another URL. I had to change the way it logins in for OpenID. To make this work, I had to change a validation of the redirect uri
