This flaw affects versions from 0.6.6 up to, but not including, 0.7.0. The vulnerability stems from improper neutralization of special elements when processing OS commands (CWE-78), allowing an attacker to inject and execute arbitrary operating system commands. While no active exploitation has been publicly reported, a successful exploit could lead to complete system compromise, data manipulation, or privilege escalation on affected Linux systems. The Computer Emergency Response Team of the Republic of Turkey (TR-CERT) has identified and reported this issue, and it carries a CVSS v3.1 base score of 7.8 (High), highlighting the significant risk it poses.
