CVE-2026-24425 (opens in a new tab)How to fix?
Upgrade twig/twig to version 3.26.0 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 callback validation for the sort, filter, map, and reduce filters when sandboxing is enabled through SourcePolicyInterface. An attacker can bypass the sandbox callback restrictions by supplying arbitrary PHP callables instead of Closure objects, as the runtime sandbox check fails to use the current template Source and can incorrectly treat sandboxed execution as non-sandboxed.
Note: This is only exploitable if all of these conditions are met:
Sandbox is not enabled globally.
Sandbox is enabled through
SourcePolicyInterface.The template uses the
sort,filter,map, orreducefilters.The callback is not a
Closure.
