Incus versions 7.0.1 prior to 7.0.2 and 7.2.0 prior to 7.5.0 are susceptible to an authorization bypass vulnerability. This flaw enables project-restricted clients to illicitly copy volumes by manipulating POST requests to the custom volumes endpoint, effectively circumventing project restrictions.
