CVE-2026-110644
CRITICAL 9.3nodejs-whisper through 0.3.1 contains an OS command injection vulnerability in convertToWavType() that allows attackers to execute commands by supplying crafted audio file paths. Attackers can provide file names containing $() command substitution or closing quotes, which are interpolated into an ffmpeg command run via shelljs exec(), executing OS commands with Node.js process privileges.
Severe if exploited (CVSS 9.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
