{"id":"CVE-2025-66508","aliases":["GHSA-7cqv-qcq2-r765","GO-2025-4207"],"url":"https://o3.security/vulnerability/CVE-2025-66508","summary":"1Panel IP Access Control Bypass via Untrusted X-Forwarded-For Headers","details":"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.","published":"2025-12-09T01:37:10.219Z","modified":"2026-08-12T03:51:24.423250047Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00228,"percentile":0.13328,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel","fixedVersion":"2.0.14"},{"ecosystem":"Go","name":"github.com/1Panel-dev/1Panel/agent","fixedVersion":"0.0.0-20251201063338-94f7d78cc976"}],"fix":{"url":"https://github.com/1Panel-dev/1Panel/commit/94f7d78cc9768ee244da33e09408017d1f68b5ed","label":"1Panel-dev/1Panel@94f7d78"},"references":[{"type":"ADVISORY","url":"https://github.com/1Panel-dev/1Panel/security/advisories/GHSA-7cqv-qcq2-r765"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/66xxx/CVE-2025-66508.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66508"},{"type":"FIX","url":"https://github.com/1Panel-dev/1Panel/commit/94f7d78cc9768ee244da33e09408017d1f68b5ed"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.423250047Z"}}
