Overview
Affected versions of this package are vulnerable to Information Exposure in the form of exposing IPv4 and IPv6 addresses of hidden services via replay attack. An attacker can de-anonymize public IP addresses by sending the messages with the same messageID to a client, which passes the message through a bloom filter, and directly to the router, which drops it due to already having seen the unique ID before. This attack is unreliable due to the length of time it takes to brute force the target router, during which time activity on the router or the network may impact the predictability of its results.
