CVE-2026-25552

Ghost CLI < 1.30.1 IP Spoofing via X-Forwarded-For Header

Published Jul 31, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
Ghost CLI before 1.30.1 contains an IP spoofing vulnerability that allows unauthenticated remote attackers to bypass rate-limiting controls by manipulating the X-Forwarded-For header through a misconfigured Nginx configuration. Attackers can append attacker-controlled values to the header chain using the $proxy_add_x_forwarded_for directive to present an arbitrary IP address, circumventing Ghost's rate-limiting mechanisms on self-hosted instances.
