How to Fix CVE-2022-23614

To remediate this vulnerability, upgrade all affected Twig/twig dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

twig/twig fixed: 2.14.11 
Upgrade twig/twig to 2.14.11
twig/twig fixed: 3.3.8 
Upgrade twig/twig to 3.3.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for twig/twig

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-23614, inspect your project dependencies for Twig/twig:

inspect dependencies for twig/twig

Analyze the terminal output to locate any version of Twig/twig in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.14.11), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Twig/twig, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# Description When in a sandbox mode, the `arrow` parameter of the `sort` filter must be a closure to avoid attackers being able to run arbitrary PHP functions. # Resolution We now disallow calling non Closure in the `sort` filter like we already did for some other filters. # Credits We would like to thank Marlon Starkloff for reporting the issue and Fabien Potencier for fixing the issue.
