Description
ProjectSend 2.0.0 before 2.7.0 contains a path validation flaw in OrphanFileScanner::isOrphan() that allows staff with import_orphans permission to treat tracked files as orphans. Attackers can submit ./ path aliases to the orphans import or delete endpoints, deleting or adopting other owners' files while bypassing delete_others_files.
