Puma web server versions from 5.5.0 up to 7.2.1 and 8.0.2 are vulnerable to source IP spoofing when the set_remote_address proxy_protocol: :v1 option is enabled and persistent connections are used. The vulnerability arises because Puma incorrectly re-parses PROXY protocol headers after each keep-alive request on the same connection, allowing an attacker to inject a second PROXY header and overwrite the REMOTE_ADDR value. This issue is fixed in versions 7.2.1 and 8.0.2. Join the discussion | GCVE Database | 07/14/2026, 20:17:00 UTC Added: 10/17/2026, 22:26:57 UTC |
