Dolibarr 21.0.0 before 24.0.0 contains an authorization bypass vulnerability caused by an inverted boolean condition in the private-project membership check within the clonetasks mass action handler in htdocs/core/actions_massactions.inc.php. Authenticated users with project creation permission but without access to a target private project can exploit the flawed !in_array() check to clone tasks into unauthorized private projects.
