Official Description

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.

Technical Analysis

CVE-2026-46628 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
