Description
NVD
ProjectSend 2.0.0 through 2.7.1 contains an incomplete authorization vulnerability in FileVersions::link() that allows staff users to share files without authorization by linking file versions. Attackers can link their file onto an intermediate revision or assign out-of-scope clients, causing moveAssignmentsToRoot() to expose protected original files to unauthorized clients.
