CyberRota Analysis

AI-Generated

The Cline Hub dashboard server prior to version 3.0.30 is vulnerable due to improper validation of the Origin header for WebSocket connections, allowing unauthorized websites to execute commands and manipulate workspace settings. This could lead to significant security breaches, including unauthorized access to sensitive data and system configurations. Organizations using Cline in their development environments should prioritize updating to version 3.0.30 to mitigate these risks.

Original NVD Description

Cline is an autonomous coding agent as an SDK, IDE extension, or CLI assistant. Prior to 3.0.30, the Cline Hub dashboard server launched by the cline dashboard command accepts WebSocket connections on the /browser endpoint without validating the Origin header, and when ROOM_SECRET is unset for local 127.0.0.1 binds, isAuthorizedBrowserRequest() allows attacker-controlled websites to send desktopCommand frames that read workspace state, mutate MCP and provider settings, and trigger command execution when a provider or model is configured. This issue is fixed in version 3.0.30.
