CVE-2026-48805: Symfony Twig

Critical severity, CVSS 9.1. EPSS: 0.5% chance of exploitation in the next 30 days.

Twig is a template language for PHP. Prior to 3.27.0, deprecated internal wrappers in src/Resources/core.php do not forward the current sandbox state to CoreExtension::checkArrow(), arraySome(), and arrayEvery(), allowing legacy calls such as twig_array_some(), twig_array_every(), and twig_check_arrow_in_sandbox() to bypass sandbox callable restrictions. This issue is fixed in version 3.27.0.

Affected products

• Symfony Twig: before 3.27.0 (fixed in 3.27.0)
