CVE-2026-46633
Twig: PHP code injection via `{% use %}` template name
publishedCWE-94
Twig is a template language for PHP. Starting in 1.15.1 and prior to 3.26.0, Compiler::string() does not escape single quotes when a template name from a {% use %} tag is placed inside a PHP single-quoted string literal, allowing a crafted template name to terminate the string and inject arbitrary PHP expressions into the compiled cache file. This issue is fixed in version 3.26.0.
