"New" objection to wormholes

String theory has nothing specific to say about information loss.
Preservation of information ("unitary evolution" from initial conditions) is basic to quantum theory.
Information loss through a wormhole is not a concern, because the location of the "lost" information is perfectly clear (on the other side of the wormhole). The info is not lost.
Information loss is concern, however, for black holes. They swallow the information, evaporate, and thereby vanish from the universe along with the info they ingested. This is the so-called "Black hole information problem".
Bottom line: There is no "wormhole information problem".
