Summary
OpenBMB Internet of Agents has a missing-authentication flaw in its WebSocket Connection Manager, in the ConnectionManager.connect function. A remote attacker may be able to reach the affected operation without the intended authentication when manipulating the agent_name argument.
OpenBMB Internet of Agents has a missing-authentication flaw in its WebSocket Connection Manager, in the ConnectionManager.connect function. A remote attacker may be able to reach the affected operation without the intended authentication when manipulating the agent_name argument.
Affected context
The issue affects the WebSocket Connection Manager in im_server/app.py in OpenBMB Internet of Agents, in the ConnectionManager.connect function. The flaw is reported in releases up to the cited commit; because the project uses rolling releases, precise affected and fixed version details are not available. Risk depends on whether the affected service is reachable by an attacker.

Exploit preconditions
- Attack surface: A remotely reachable WebSocket service exposing the affected connection function
- Required access: The report indicates that authentication is missing for the affected operation; valid credentials may not be required to reach it
- Trigger point: Handling of the
agent_nameargument byConnectionManager.connect - Why exploitation is possible: The connection operation may be reachable without an effective authentication check
- Attack surface: A remotely reachable WebSocket service exposing the affected connection function
- Required access: The report indicates that authentication is missing for the affected operation; valid credentials may not be required to reach it
- Trigger point: Handling of the
agent_nameargument byConnectionManager.connect - Why exploitation is possible: The connection operation may be reachable without an effective authentication check
Why this happens
The reported behavior is consistent with CWE-306: Missing Authentication for Critical Function. The connection function does not adequately require authentication before processing the affected request. This also relates to CWE-287: Improper Authentication, which covers failures to correctly verify identity or access.

Potential impact
- An attacker may be able to invoke the affected connection operation without authentication.
- Unauthorized connections could expose or affect application functionality, depending on the service's design and permissions.
- Further impact could occur if the operation provides access to privileged actions or sensitive data.

General mitigation guidance
Defensive patterns include requiring authentication and authorization at the server-side boundary for every connection operation, rather than relying on caller-supplied identifiers such as agent_name. Treat connection parameters as untrusted, validate them against the authenticated identity and permitted resources, and default to denying access when identity or authorization checks fail. Apply least privilege to services and connection handlers so that an authentication failure cannot grant broader capabilities.

How teams detect issues like this
- Review connection-handling code for paths that accept requests before authenticating the caller.
- Use static analysis and code review to identify sensitive operations that lack authentication or authorization checks.
- Enforce policy checks that require authenticated identity and resource-level authorization before WebSocket actions proceed.
- Monitor for connection attempts or sensitive operations that occur without an authenticated principal, and investigate unexpected access patterns.
- Automated code review tools may help flag missing access-control checks.
