Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 7.1.0 until 7.4.12 and 8.0.12, Cas2Handler builds the CAS service parameter from Request::getSchemeAndHttpHost(), which reflects an attacker-controlled Host header when framework.trusted_hosts is not configured; an attacker controlling another application registered with the same CAS server can replay a victim ticket against the Symfony application and authenticate as the victim. This issue is fixed in versions 7.4.12 and 8.0.12.

 https://cve.radiocsirt.org/vuln/ghsa-j8gj-9rm5-4xhx GHSA-j8gj-9rm5-4xhx — Symfony's Cas2Handler Derives CAS service URL from Client Host Header → Cross-Service Ticket Replay 2026-10-08T03:25:32.796703+00:00

Affected: Packagist: symfony/security-http, Packagist: symfony/symfony

`Cas2Handler` builds this `service` parameter from `Request::getSchemeAndHttpHost()`, which reflects the attacker-controlled HTTP `Host` header whenever Symfony's `framework.trusted_hosts` setting is not configured (the default). An attacker who controls any *other* application registered with the same CAS server can replay a victim's ticket against the Symfony application, with a spoofed `Host` header, and be authenticated as that victim.

### Resolution

A new required `service_url` configuration option is introduced on `Cas2Handler`. The CAS `service` parameter sent to the validation endpoint is now built from this configured URL instead of being derived from the request's `Host` header, preventing cross-service ticket replay via Host header spoofing.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/5ba145dba702404801bdf9e7e8d6df170060d541) for branch 7.4.

### Credits

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