Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, UrlGenerator validates route parameters against a pattern built as ^ plus the raw requirement plus $; with ungrouped alternations, middle alternatives match as unanchored substrings, allowing a value such as //evil.com to satisfy a common locale requirement and generate a protocol-relative off-site URL. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.

 https://cve.radiocsirt.org/vuln/ghsa-72xp-p242-47p9 GHSA-72xp-p242-47p9 — Symfony has a UrlGenerator Route-Requirement Bypass via Unanchored Regex Alternation → Off-Site //host URL Injection 2026-10-03T09:48:27.152979+00:00

Affected: Packagist: symfony/routing, Packagist: symfony/symfony

### Description

Symfony routes can declare a requirements regex per path parameter, e.g. a route `/{_locale}/blog` with `requirements: { _locale: 'en|fr|de' }`. The Twig `path()` / `url()` helpers (backed by `UrlGenerator`) validate supplied parameter values against that regex before building the URL.

UrlGenerator constructs the validation pattern as `'#^'.$req.'$#'`, where `$req` is the raw requirement string. For a requirement expressed as an alternation, e.g. `_locale: 'ar|bg|...|vi|...|zh_CN'` (very common), `^` and `$` anchor only the first and last alternatives, so any middle alternative matches as an unanchored substring. A value like `/evil.com` satisfies the requirement (because it contains `vi`), and the generated path becomes `//evil.com/...`: a protocol-relative URL the browser navigates off-site.

### Resolution

The `UrlGenerator` class now wraps the requirement in a non-capturing group so the `^` and `$` anchors apply to the whole alternation.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/bcf487c22f3240ba994124e0e0fe8616f3cfc47a) for branch 5.4.

### Credits

Symfony would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and providing the fix.
