Recommendation: Plan a near-term fix — a public PoC already exists.

Webgrind 1.1 contains a remote command execution vulnerability that allows unauthenticated attackers to inject OS commands via the dataFile parameter in index.php. Attackers can execute arbitrary system commands by manipulating the dataFile parameter, such as using payload '0%27%26calc.exe%26%27' to execute commands on the target system.
