Twig is a template language for PHP. Prior to 3.26.0, the deprecated spaceless filter is registered as safe for HTML, causing Twig autoescaping to emit attacker-controlled markup unescaped when spaceless is applied to untrusted input. This issue is fixed in version 3.26.0.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
