Authentication throttling bypass via spoofed forwarded IP
Published Sep 18, 2026 · Updated Sep 18, 2026
Improper authentication throttling in Saleor allows remote attackers to bypass login delays by spoofing a forwarded client IP. The get_client_ip function accepts the first syntactically valid X-Forwarded-For value and uses it to key failed-login counters without identifying a trusted proxy hop. The bypass applies when a proxy appends the real address after attacker-controlled values, allowing repeated password attempts without cumulative per-IP backoff.
