This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

Twig versions 2.16.x and 3.9.0 through 3.25.x contain a sandbox bypass vulnerability when using a SourcePolicyInterface that allows attackers with template rendering capabilities to pass arbitrary PHP callables to sort, filter, map, and reduce filters. Attackers can exploit the runtime check that fails to use the current template source to bypass sandbox restrictions and execute arbitrary code when the sandbox is enabled through a source policy rather than globally.

Remediation

Check the references section for vendor advisories and patches from symfony. Update twig to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
