{"id":"CVE-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":["GHSA-wjx2-9fpq-8997"],"modified":"2026-08-04T11:50:30.216457772Z","published":"2026-07-31T18:12:40.072Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-348"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25552.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25552.json"},{"type":"ADVISORY","url":"https://github.com/TryGhost/Ghost-CLI/security/advisories/GHSA-wjx2-9fpq-8997"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25552"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/ghost-cli-ip-spoofing-via-x-forwarded-for-header"},{"type":"PACKAGE","url":"https://github.com/TryGhost/Ghost-CLI"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tryghost/ghost-cli","events":[{"introduced":"0"},{"fixed":"6c711179d9669c1938aa506f92a82c602d6c202e"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"1.30.1"}]}}],"versions":["v1.30.0","v1.29.3","v1.29.2","v1.29.1","v1.29.0","v1.28.6","v1.28.4","v1.28.3","v1.28.2","v1.28.1","v1.28.0","v1.27.1","v1.27.0","v1.26.1","v1.26.0","v1.25.3","v1.25.2","v1.25.1","v1.25.0","v1.24.1","1.24.0","1.23.1","1.23.0","1.22.0","1.21.1","1.21.0","1.20.0","1.19.3","1.19.2","1.19.1","1.19.0","1.18.2","1.18.1","1.18.0","1.17.4","1.17.2","1.17.1","1.17.0","1.16.3","1.16.2","1.16.1","1.16.0","1.15.3","1.15.2","1.15.1","1.15.0","1.14.1","1.14.0","1.14.0-beta.0","1.13.1","1.13.0","1.13.0-beta.1","1.13.0-beta.0","1.12.1","1.12.0","1.12.0-beta.1","1.12.0-beta.0","1.11.0","1.10.1","1.10.0","1.10.0-rc.1","1.10.0-rc.0","1.10.0-beta.1","1.10.0-beta.0","1.9.9","1.9.8","1.9.7","1.9.6","1.9.5","1.9.4","1.9.3","1.9.2","1.9.1","1.9.0","1.8.1","1.8.0","1.7.3","1.7.2","1.7.1","1.7.0","1.6.0","1.5.2","1.5.1","1.5.0","1.4.2","1.4.1","1.4.0","1.3.0","1.2.1","1.2.0","1.1.3","1.1.2","1.1.1","1.1.0","1.0.3","1.0.2","1.0.1","1.0.0","1.0.0-rc.4","1.0.0-rc.3","1.0.0-rc.2","1.0.0-rc.1","1.0.0-beta.6","1.0.0-beta.5","1.0.0-beta.4","1.0.0-beta.3","1.0.0-beta.2","1.0.0-beta.1","1.0.0-alpha.19","1.0.0-alpha.18","1.0.0-alpha.17","1.0.0-alpha.16","1.0.0-alpha.15","1.0.0-alpha.14","1.0.0-alpha.13","1.0.0-alpha.12","1.0.0-alpha.11","1.0.0-alpha.10","1.0.0-alpha.9","1.0.0-alpha.8","1.0.0-alpha.7","1.0.0-alpha.6","1.0.0-alpha.5","1.0.0-alpha.4","1.0.0-alpha.3","1.0.0-alpha.2","1.0.0-alpha.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25552.json"}}],"schema_version":"1.8.0","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"}]}
