It allows an authenticated local attacker to inject unauthorized commands via the micomd executable, potentially triggering unintended functionalities and generating malicious CAN frames on the vehicle's M-CAN bus. With a CVSS score of 7.8, this vulnerability poses a significant risk due to its high impact on confidentiality, integrity, and availability, despite requiring local access and low privileges. While not actively exploited in the wild, a Metasploit module named KOFFEE exists, indicating exploitability, though there is no public community discussion or media coverage.
