On this page
Password Pusher from 1.49.0 before 2.17.0 contains an IP spoofing vulnerability that allows remote clients to forge the recorded request IP via unanchored trusted-proxy regular expressions. Clients in 110.0.0.0/8 or 210.0.0.0/8, or connecting directly, can supply X-Forwarded-For values to falsify audit log entries and shift password generator rate limits.
