CVE-2026-116136
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.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
Description
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.
