php-twig: Twig is a template language for PHP
CVE-2026-46637 is fixed in php-twig on 1 platform, first by DEBIAN-CVE-2026-46637, released May 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Twig is a template language for PHP. Prior to 3.26.0, several filters in twig/markdown-extra and twig/cssinliner-extra are registered with is_safe => [all], causing Twig to treat plain text or HTML output as safe in HTML, JavaScript, CSS, URL, and other contexts where the output is not properly escaped. This issue is fixed in version 3.26.0.
