Details
PluginScript attempts to chroot the plugin to the repoManagerRoot, this root is frequently / (the system root) in standard configurations or when using --root. If the chroot target is /, it is a no-op, allowing the traversed path to execute host binaries (like /bin/bash) with root privileges.
