CVE-2026-67614: Use of Hard-coded Credentials in usmannasir cyberpanel
CyberPanel versions prior to 3.0.0 contain a critical vulnerability due to a hard-coded JWT secret in the WebTerminal FastAPI SSH service. This flaw allows unauthenticated remote attackers to forge valid JWT authentication tokens, specifying ssh_user=root, to gain an interactive root shell via WebSocket on port 8888 without valid credentials.
AI Analysis
Technical Summary
CVE-2026-67614 is a critical security vulnerability in CyberPanel before version 3.0.0. The issue arises from a hard-coded JWT secret used by the WebTerminal FastAPI SSH service. Attackers can exploit this by crafting forged JWT tokens signed with the hardcoded secret, specifying ssh_user=root, which enables them to authenticate to the terminal service remotely without any legitimate credentials. This results in unauthorized root shell access via WebSocket on port 8888, effectively allowing full control over the affected system.
Potential Impact
Successful exploitation grants unauthenticated attackers root-level access to the affected CyberPanel server through the WebTerminal service. This compromises the confidentiality, integrity, and availability of the system, allowing complete control and potential further malicious activities.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to port 8888 and disable the WebTerminal FastAPI SSH service if possible to reduce exposure.
