Official Description

Twig is a template language for PHP. 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.

Risk Analysis

This critical vulnerability in Twig prior to version 3.26.0, with a CVSS score of 9.8, allows for arbitrary PHP expression injection into compiled cache files. This is due to improper escaping of single quotes in template names from {% use %} tags.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable (AV:N) and has low attack complexity (AC:L), making it a significant concern.

Recommended Action

Upgrade Twig to version 3.26.0 or later. Ensure that all template names are properly escaped before being embedded in PHP string literals within compiled cache files.
