{"cve":"CVE-2025-66508","nvd":{"published":"2025-12-09T16:18:19.437","modified":"2026-10-14T21:10:00.183","status":"Analyzed","description":"1Panel is an open-source, web-based control panel for Linux server management. 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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-290"],"references":["https://github.com/1Panel-dev/1Panel/commit/94f7d78cc9768ee244da33e09408017d1f68b5ed","https://github.com/1Panel-dev/1Panel/security/advisories/GHSA-7cqv-qcq2-r765"],"products":["fit2cloud:1panel"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-66508","score":0.00253,"percentile":0.16639,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7cqv-qcq2-r765","url":"https://osv.dev/vulnerability/GHSA-7cqv-qcq2-r765","summary":"1Panel IP Access Control Bypass via Untrusted X-Forwarded-For Headers","modified":"2025-12-17T01:01:43.236248Z","packages":[{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel","purl":"pkg:golang/github.com/1Panel-dev/1Panel","ranges":["<2.0.14"],"fixed":["2.0.14"]},{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel/agent","purl":"pkg:golang/github.com/1Panel-dev/1Panel/agent","ranges":["<0.0.0-20251201063338-94f7d78cc976"],"fixed":["0.0.0-20251201063338-94f7d78cc976"]}]},{"id":"GO-2025-4207","url":"https://osv.dev/vulnerability/GO-2025-4207","summary":"1Panel IP Access Control Bypass via Untrusted X-Forwarded-For Headers in github.com/1Panel-dev/1Panel","modified":"2026-03-03T04:57:46.442949Z","packages":[{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel","purl":"pkg:golang/github.com/1Panel-dev/1Panel","ranges":["<2.0.14+incompatible"],"fixed":["2.0.14+incompatible"]},{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel/agent","purl":"pkg:golang/github.com/1Panel-dev/1Panel/agent","ranges":["<0.0.0-20251201063338-94f7d78cc976"],"fixed":["0.0.0-20251201063338-94f7d78cc976"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
