CyberRota Analysis

AI-Generated

Versions of obot prior to v0.21.1 are vulnerable due to inadequate enforcement of Access Control Rules on the /mcp-connect endpoint, allowing any authenticated user with the server ID to connect to restricted MCP servers. This flaw enables attackers to bypass authorization checks, potentially leading to unauthorized access and manipulation of sensitive backend systems via MCP tool calls using stored OAuth credentials. Organizations utilizing affected versions should prioritize immediate updates to mitigate this critical security risk.
