Name of the Vulnerable Software and Affected Versions picotts versions prior to 0.1.1

Description The issue arises when attacker-controlled user input is given to the say 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 0.1.1, as a temporary workaround, consider disabling the say function until a patch is available. Restrict access to the child process exec function to minimize the risk of exploitation. Avoid using the say function with untrusted input until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
