Overview
Affected versions of this package are vulnerable to Missing Origin Validation in WebSockets via the operations API response, which includes secret values used for authenticating WebSocket connections. An attacker can execute arbitrary commands with the privileges of another user by hijacking active terminal or console sessions through the use of these secret values. This is only exploitable if the attacker has read permissions for the project and a victim with higher privileges opens a terminal or console session, allowing the attacker to intercept the WebSocket connection at the correct timing.
