Summary
Beganovich snappdf from 1.1.0 before 6.1.0 contains an OS command injection flaw on Windows (CWE-78). The setUrl() value is passed unescaped to PHP exec() through executeOnWindows(), so cmd.exe metacharacters are not neutralized. An unauthenticated remote attacker who influences the rendered URL can run commands as the PHP process.
