Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was found in OpenBMB XAgent 1.0.0. This impacts the function check_user of the file XAgentServer/application/websockets/share.py of the component ShareServer WebSocket Endpoint. Performing a manipulation of the argument interaction_id results in missing authentication. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
OpenBMB XAgent 1.0.0 ShareServer WebSocket endpoint allows remote authentication bypass through manipulation of the interaction_id parameter in the check_user function, enabling unauthenticated attackers to access protected resources with low confidentiality, integrity, and availability impact. Publicly available exploit code exists, the vendor was contacted but did not respond, and active exploitation remains possible.

Vulnerability AssessmentAI
| Risk Assessment | The CVSS v4.0 score of 6.9 reflects a low attack complexity, no privilege requirement, and network-accessible vector (AV:N, AC:L, PR:N), indicating trivial exploitation prerequisites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker crafts a WebSocket connection to the ShareServer endpoint and sends a manipulated interaction_id parameter that bypasses the check_user validation logic. With no authentication required (PR:N in CVSS vector) and trivial network-level complexity, the attacker gains immediate access to protected interaction resources without credentials. … |
| Remediation | Immediate patching is the primary mitigation; however, no vendor-released patch has been identified at the time of analysis, and the vendor has not responded to early disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
