CVE-2026-46635
Medium
Description
Twig is a template language for PHP. Prior to 3.26.0, the column filter passes object arrays to PHP array_column(), which reads public and magic properties without reaching CoreExtension::getAttribute() or SandboxExtension::checkPropertyAllowed(), allowing an untrusted template author with column in allowedFilters to read properties that are not in the sandbox allowlist. This issue is fixed in version 3.26.0.
