CVE-2026-65916

CyberPanel before 3.0.0 contains a hard-coded JWT secret vulnerability in the WebTerminal FastAPI SSH service that allows unauthenticated remote attackers to forge valid authentication tokens and obtain an interactive root shell via WebSocket on port 8888. Attackers can craft a forged JWT signed with the hardcoded secret value, specifying ssh_user=root, to authenticate to the terminal service without any valid credentials and receive a root shell.

CyberPanel versions prior to 2.4.5 contain an authentication bypass vulnerability in the AI Scanner worker API endpoints that allows unauthenticated remote attackers to write arbitrary data to the database by sending requests to /api/ai-scanner/status-webhook and /api/ai-scanner/callback. Attackers can exploit the lack of authentication checks to cause denial of service through storage exhaustion, corrupt scan history records, and pollute database fields with malicious data.

CyberPanel v1.9.1 contains a path traversal vulnerability in the compress method exposed through the /filemanager/controller endpoint. An authenticated remote attacker with ownership of any configured domain can supply absolute or otherwise out-of-scope file paths in the listOfFiles JSON property, together with attacker-controlled basePath and compressedFileName values, in a method=compress request.

CyberPanel 1.9.1 contains a path traversal vulnerability in the readFileContents method of the /filemanager/controller endpoint. An authenticated remote attacker with ownership of any configured domain can supply an arbitrary absolute or out-of-scope path in the fileName JSON property.

CyberPanel before 2.4.4 has no logging for actions that could potentially manipulate the child domains list. The lack of logging makes it difficult to detect unauthorized changes.

CyberPanel before 2.4.4 attempts to detect an "alais" domain (i.e., a second domain that serves the same content as a primary domain; normally spelled "alias") via an ORM query filter rather than a Python "if" statement.

CyberPanel before 2.4.4 omits a "return 0" that is required by the business logic. This may lead to incorrect function behavior.

CyberPanel before 3.0.5 fails to enforce two-factor authentication on API endpoints, allowing attackers to bypass TOTP requirements using password-derived tokens. An attacker who obtains an administrator's password can derive API tokens and perform administrative operations or create authenticated sessions without the second factor.
