CVE-2026-48808 (opens in a new tab)How to fix?
Upgrade twig/twig to version 3.27.0 or higher.
Overview
twig/twig is a flexible, fast, and secure template language for PHP.
Affected versions of this package are vulnerable to Incorrect Authorization via the CoreExtension::column() filter when sandboxing is enabled through SourcePolicyInterface. An attacker can bypass the sandbox property restrictions because column() fails to propagate the current Source when invoking SandboxExtension::checkPropertyAllowed(), causing source-policy sandbox decisions to be lost and property authorization checks to be skipped. This allows reading arbitrary public or magic properties of objects exposed to the template, regardless of the configured SecurityPolicy::$allowedProperties.
Note:
This is only exploitable when sandboxing is enabled through SourcePolicyInterface and the column filter is permitted. Globally enabled sandbox mode is not affected.
This vulnerability is a bypass of the fix for CVE-2026-46635.
