Summary
The desmondmorris node-tesseract package up to 0.2.7 contains an OS command injection flaw (CWE-78) in the process function of lib/tesseract.js. Attacker-controlled input to the image argument is not neutralized, so a remote attacker can inject operating system commands without privileges or user interaction. The exploit has been publicly disclosed, and a public exploit is linked in the references. The project was informed through an issue report but has not responded.
