An attacker can send crafted network requests to a network\u2011accessible Jaaz instance, causing the service to execute arbitrary commands supplied in the request.

The CVSS score is 7.3, indicating a high severity, but the description indicates an unauthenticated, network\u2011based remote code execution with high impact on confidentiality, integrity, and availability. Because the flaw is reachable over the network without authentication, the risk is considered high and exploitation is likely if the service is exposed to untrusted users."}}}}, "created": "2026-04-15T21:02:35.138666+00:00", "title": "Remote Command Execution via MCP STDIO in Jaaz\u00a01.0.30", "updated": "2026-04-15T22:30:16.080944+00:00", "vendors": ["jaaz", "jaaz$PRODUCT$jaaz"]}
