Versions 2.0.14 and below use Gin's default configuration which trusts all IP addresses as proxies (TrustedProxies = 0.0.0.0/0), allowing any client to spoof the X-Forwarded-For header. Since all IP-based access controls (AllowIPs, API whitelists, localhost-only checks) rely on ClientIP(), attackers can bypass these protections by simply sending X-Forwarded-For:  127.0.0.1 or any whitelisted IP. This renders all IP-based security controls ineffective. This issue is fixed in version 2.0.14.","state":0,"publishedAt":"2025-12-09T01:37:10.219+00:00","modifiedAt":"2025-12-09T16:03:08.608+00:00","affected":[{"ecosystem":"Vendor product","name":"1Panel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"1Panel-dev\",\n                    \"product\": \"1Panel\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.14\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/1Panel-dev/1Panel/security/advisories/GHSA-7cqv-qcq2-r765","https://github.com/1Panel-dev/1Panel/commit/94f7d78cc9768ee244da33e09408017d1f68b5ed"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-66508","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-66508","identifiers":["CVE-2025-66508"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
