symfony: Symfony is a PHP framework for web and console applications and a set of reusable PHP components
CVE-2026-45065 is fixed in symfony on 1 platform, first by DEBIAN-CVE-2026-45065, released May 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
