{"id":"BIT-ghost-2026-25552","summary":"Ghost CLI \u003c 1.30.1 IP Spoofing via X-Forwarded-For Header","details":"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.","aliases":["CVE-2026-25552","GHSA-wjx2-9fpq-8997"],"modified":"2026-10-01T10:10:48.883569291Z","published":"2026-10-01T09:24:12.088Z","database_specific":{"cpes":["cpe:2.3:a:ghost:ghost:*:*:*:*:*:node.js:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/TryGhost/Ghost-CLI/security/advisories/GHSA-wjx2-9fpq-8997"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25552"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ghost-cli-ip-spoofing-via-x-forwarded-for-header"}],"affected":[{"package":{"name":"ghost","ecosystem":"Bitnami","purl":"pkg:bitnami/ghost"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.30.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/ghost/BIT-ghost-2026-25552.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
