This link is maintained to preserve external references.\n\n## Original Description\nIn the Golang Chi web framework, the ClientIPFromXFF middleware skips any X-Forwarded-For entry in a configured trusted CIDR but never verifies that the direct TCP peer in http.Request.RemoteAddr belongs to that CIDR. A client that can reach the Go server directly can therefore append a trusted-looking proxy address and choose the client IP returned by middleware.GetClientIP.\n\nThis issue affects chi before 5.4.0.","public_affected_ranges":["<= 5.3.2"]}],"null_published_at":"2026-10-31T22:13:48.415Z","source_updated_at":"2026-10-23T20:56:30.000Z","source_disclosed_at":"2026-10-21T15:42:31.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T22:07:08.657Z"}],"next_cursor":null,"snapshot_revision":"42594"}
