Colanode server through 0.4.7 contains a path traversal vulnerability that allows authenticated users to read arbitrary .jpeg files by supplying an encoded traversal sequence in avatarId. Attackers can send percent-encoded ../ sequences to GET /client/v1/avatars/:avatarId to escape the avatars directory and read .jpeg files belonging to other workspaces.
