CVE-2025-66219 is a critical command injection vulnerability affecting versions 0.2.1 and prior of the 'willitmerge' command-line tool. This flaw arises from the insecure use of the 'exec' child process execution API, which concatenates user-controlled input, allowing for arbitrary command execution. With a CVSS score of 9.8 (Critical), this vulnerability poses a significant risk, enabling unauthenticated attackers to achieve full compromise (confidentiality, integrity, availability) of affected systems with low attack complexity. There is currently no public fix available, and while there are no known active exploits or public exploit code, the vulnerability has garnered some community discussion.
