Summary

The custom_url_set rule (used on redirect_uris, post_logout_redirect_uris and allowed_origins for non-native clients) rejected any https URL whose hostname contains a hyphen and has an explicit port, e.g. https://macbook-air.tail3c93e5.ts.net:10000/auth/callback, returning redirect_uris: validation.custom_url_set.

Root cause: in CustomValidator::validateSslurl the host part of the regex ([\w.:@]+) did not allow -, so the host match stopped at the first hyphen and the remainder had to match the path part, which does not allow :. Hyphenated hosts without a port only passed by accident (the rest of the hostname matched as "path").

Fix

  • Backend: allow - in the host part: ([\w@][\w.:@\-]+). The first host character still cannot be -, and the https requirement is unchanged.
  • Edit client UI: the Post Logout URIs field (logout_options.js) validated entries with a copy of the same regex, so TagsInput silently dropped hyphenated host + port URLs before they reached the API. It now uses the same host class as the backend. redirect_uris and allowed_origins in the UI already validate with new URL() and were not affected.

Tests

New tests/unit/CustomUrlSetValidatorTest.php runs the real custom_url_set rule through CustomValidator:

  • accepts a hyphenated host with port (the reported URL), plus previously valid forms (IP:port, localhost:port, Netlify -- hosts, plain hosts)
  • rejects http, scheme-less URLs and hosts starting with -
  • comma-separated sets: accepted when all valid, rejected when any entry is invalid

Fails before the fix (reported URL rejected), 12/12 pass after.

./vendor/bin/phpunit tests/unit/CustomUrlSetValidatorTest.php

Manual check for the UI: on Edit Client → Logout Options, adding https://macbook-air.tail3c93e5.ts.net:10000/logout to Post Logout Uris now creates the tag; http://… and https://-host… are still not added.

Summary by CodeRabbit

  • New Features
    • HTTPS redirect URL validation now accepts hostnames containing hyphens and @ characters, while continuing to validate URL schemes and comma-separated URL sets. This supports a broader range of hostname formats when configuring redirect URLs.

…lurl

The host part of the sslurl regex did not allow '-' and the path part does
not allow ':', so any https URL with a hyphenated hostname and a port
(e.g. https://macbook-air.example.ts.net:10000/auth/callback) failed the
custom_url_set rule on redirect_uris / allowed_origins.

Change: Bug fix

Merge Risk: 🔵 Low · up to 931e2

Hyphenated HTTPS URLs can be accepted, but the validator also admits misleading redirect URLs with embedded credentials. Remove @ from the hostname pattern before merging, or explicitly accept that bounded risk.

…t uris

The post logout redirect URI validator in the edit client UI still used the
old sslurl regex, whose host part did not allow '-', so TagsInput silently
dropped URLs like https://macbook-air.example.ts.net:10000/logout even though
the API now accepts them.
