AI-suggested
Upgrade Twig to version 3.26.0 or later, where this issue is fixed. No other mitigations are specified or recommended.
Description
Twig, a PHP template language, has a vulnerability in versions prior to 3.26.0 where the deprecated spaceless filter is incorrectly marked as safe for HTML. This causes the autoescaping feature to output attacker-controlled markup unescaped when spaceless is applied to untrusted input. The issue is fixed in version 3.26.0.
