{"id":"DEBIAN-CVE-2026-46640","details":"Twig is a template language for PHP. From 3.15.0 until 3.26.0, _self.(\u003cstring\u003e) 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.
