Twig: Arbitrary PHP code execution via `_self.(<string>)` macro-reference compilation

Twig is a template language for PHP. From 3.15.0 until 3.26.0, _self.(<string>) and import-alias dynamic attribute syntax can concatenate an attacker-controlled string into a MacroReferenceExpression name without identifier validation, causing raw PHP to be emitted into the generated template source and executed at template-load time. This issue is fixed in version 3.26.0.

Affected products

Twig
  • ==>= 3.15.0, < 3.26.0
