PairDrop through 1.11.2 contains an IP spoofing vulnerability in Peer._setIP that allows remote attackers to join other networks' discovery rooms by supplying a forged cf-connecting-ip header. Attackers who know a victim's public IP can appear as a local device on self-hosted instances not behind Cloudflare to send or receive files.
