CVE-2025-66508

CVSS v3.1

6.5

Medium

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
Name of the Vulnerable Software and Affected Versions 1Panel versions 2.0.14 and below
Description 1Panel is a web-based control panel for Linux server management. Versions 2.0.14 and below are configured to trust all IP addresses as proxies, allowing attackers to spoof the X-Forwarded-For header. IP-based access controls, including AllowIPs, API whitelists, and localhost-only checks, rely on the ClientIP() function and can be bypassed by sending a manipulated X-Forwarded-For header, such as X-Forwarded-For: 127.0.0.1 or any whitelisted IP. This effectively disables all IP-based security controls.
Recommendations Update to a version later than 2.0.14.
