Description
Dolibarr contains an authorization bypass vulnerability in the clonetasks mass action that allows authenticated users with project creation permissions to clone tasks into private projects they are not authorized to access. An inverted boolean condition in the private-project membership check within actions_massactions.inc.php causes the authorization flag to be set for unauthorized users, allowing attackers to supply a user-controlled projectid POST parameter to create task records in any private project.
