CVE-2026-46628

medium

Description

Twig is a template language for PHP. Prior to 3.26.0, the deprecated spaceless filter is registered as safe for HTML, causing Twig autoescaping to emit attacker-controlled markup unescaped when spaceless is applied to untrusted input. This issue is fixed in version 3.26.0.
