Recommendation: Monitor — no exploitation signal at the moment.
Vvveb prior to 1.0.8.1 contains a code injection vulnerability in the installation endpoint where the subdir POST parameter is written unsanitized into the env.php configuration file without escaping or validation. Attackers can inject arbitrary PHP code by breaking out of the string context in the define statement to achieve unauthenticated remote code execution as the web server user.
