Twig: Sandbox property allowlist bypass via the `column` filter under `SourcePolicyInterface`

Published Jul 14, 2026 · Updated Jul 15, 2026 · Assigned by GitHub_M

Description

Twig is a template language for PHP. Prior to 3.27.0, the column filter passes the active sandbox state as a boolean but does not forward the current Source to SandboxExtension::checkPropertyAllowed(), so SourcePolicyInterface decisions are lost and a template author can read public or magic properties not allowed by the sandbox policy. This issue is fixed in version 3.27.0.
