The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to an error within the experimental permission model when the --allow-fs-read flag is used with a non-* argument. An inadequate permission model fails to restrict file watching through the fs.watchFile API and result in an ability of a remote user to monitor files that they do not have explicit read access to.
