CVE-2026-48805 (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 deprecated twig_array_some(), twig_array_every(), and twig_check_arrow_in_sandbox() helper functions. An attacker can bypass the sandbox callback restrictions by supplying non-Closure callables to twig_array_some() or twig_array_every(), as these wrappers fail to propagate the sandbox state and invoke CoreExtension::arraySome() / arrayEvery() with sandbox enforcement disabled.
Note: Compiled Twig templates are not affected. This issue is only exploitable if an application directly uses the deprecated twig_* helper functions with a sandboxed Environment.
