Summary

Drupal Custom Formatters versions from 0.0.0 before 4.2.1 define privileges with unsafe actions (CWE-267), which lets users gain privileges they should not have. An attacker who already has high privileges on the network can escalate privileges with no user interaction, and the impact is high on confidentiality, integrity and availability. The sources do not report known exploitation.
