CVE-2025-65328 (GCVE-0-2025-65328)
Vulnerability from cvelistv5 – Published: 2026-01-05 00:00 – Updated: 2026-01-05 21:08
VLAI?
Summary
Mega-Fence (webgate-lib.*) 25.1.914 and prior trusts the first value of the X-Forwarded-For (XFF) header as the client IP without validating a trusted proxy chain. An attacker can supply an arbitrary XFF value in a remote request to spoof the client IP, which is then propagated to security-relevant state (e.g., WG_CLIENT_IP cookie). Deployments that rely on this value for IP allowlists may be bypassed.
Severity ?
