MISP’s importModule() path used getEnabledModule() to resolve a single import module by name, but this lookup did not enforce the per-organisation module restriction checked by getEnabledModules(). As a result, an authenticated user from an organisation that was not allowed to use a module restricted via Plugin.Import__restrict could still invoke that import module directly if they knew its name.
This could allow unauthorised access to restricted import-module functionality and, depending on the module and the user’s event permissions, may allow unauthorised import or modification of event data through a module that should have been unavailable to the user’s organisation.
