Name of the Vulnerable Software and Affected Versions Bert-VITS2 versions 2.3 and earlier

Description The issue arises from user input being directly used in a command executed with subprocess.run(cmd, shell=True) in the bert gen function, leading to arbitrary command execution. This is due to the data dir variable being used without proper sanitization.

Recommendations For Bert-VITS2 versions 2.3 and earlier, as a temporary workaround, consider disabling the bert gen function until a patch is available. Restrict access to the data dir variable to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
