Summary

Drupal core versions from 8.9.0 before 10.6.19, from 11.0.0 before 11.3.19, from 11.4.0 before 11.4.10, and from 12.0.0-alpha1 before 12.0.0-beta2 are affected. Unsafe reflection (CWE-470) lets externally controlled input select classes or code to run. An unauthenticated remote attacker can exploit this with high complexity to take control of the affected system.
