This exploits a Drupal property injection in the Forms API. Drupal 6.x, < 7.58, 8.2.x, < 8.3.9, < 8.4.6, and < 8.5.1 are vulnerable.
Drupal before 7.58, 8.x before 8.3.9, 8.4.x before 8.4.6, and 8.5.x before 8.5.1 allows remote attackers to execute arbitrary code because of an issue affecting multiple subsystems with default or common module configurations.

Assessed Attacker Value: 4 Assessed Exploitability: 5 busterb at 2019-05-09T17:57:36.446335Z reported: Many versions were vulnerable, and the vulnerability was in a well-used API. The exploit took some time to develop due to a need for a deep understanding of Drupal internals (see blog post in references).
