CVE-2026-100390 PUBLISHED

Zoraxy 3.2.3 through 3.3.4 Client IP Spoofing via X-Forwarded-For IPv6

Assigner: VulnCheck
Reserved: 25.09.2026 Published: 25.09.2026 Updated: 25.09.2026

Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access controls.
