CVE-2026-45074

Severity: High · CVSS 7.6
Published: Jul 14, 2026, 6:17:16 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.49% · Oct 25, 2026

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.
