CVE-2026-46627
Twig is a template language for PHP.
Impact
Twig is a template language for PHP. Prior to 3.26.0, the Twig sandbox does not prevent a template from consuming CPU, memory, or wall-clock time, even under the strictest allow-list, allowing untrusted templates to cause resource exhaustion. This issue is addressed in version 3.26.0 by documenting that the sandbox does not protect against resource exhaustion.
