CVE-2026-55584

phpSysInfo versions ≤ 3.4.5 contain an IP allowlist bypass in the PSI_ALLOWED check within read_config.php. The vulnerable code resolves the client IP from attacker-controlled X-Forwarded-For and Client-IP headers before falling back to REMOTE_ADDR, with no trusted-proxy concept. A remote unauthe...
