Overview
thelounge is a self-hosted Web IRC client.
Affected versions of this package are vulnerable to Information Exposure due to improper handling of user identity verification on port 113, when multiple connections use the same local port number. An attacker can obtain a list of usernames by scanning the range of local ports, exploiting the non-unique and public nature of the ident information.
