Prior to 4.2.4, the share creation and update checks in server/handles/sharing.go use strings.HasPrefix(requested_path, user.BasePath) without enforcing a directory separator boundary. An authenticated user with CanShare permission and a BasePath such as /base can submit a sibling path such as /base2/secret.txt, create a share for the out-of-scope file, and use the public share download or list handlers to read data outside the assigned directory.
