Name of the Vulnerable Software and Affected Versions ps-visitor versions prior to 0.0.3

Description The issue arises when attacker-controlled user input is given to the kill function, allowing an attacker to execute arbitrary commands due to the use of the child process exec function without input sanitization.

Recommendations For versions prior to 0.0.3, update to version 0.0.3 or later to resolve the issue. As a temporary workaround, consider disabling the kill function until a patch is available. Restrict access to the child process exec function to minimize the risk of exploitation.
