An allowlist exists for commands, yet certain permitted commands such as npm and npx interpret flag arguments that can be abused to execute arbitrary OS commands, bypassing the intended command restrictions. This flaw enables a malicious actor to run any command with the privileges of the Upsonic process, potentially compromising the host system fully.", "risk_and_exploitability": "The vulnerability allows remote execution of arbitrary system commands using the Upsonic MCP interface. An attacker who can submit MCP tasks, either remotely or via local privileges, could trigger execution with the privileges of the Upsonic process. The CVSS score is 9.8, indicating a critical severity, while the EPSS score is less than 1%, showing a very low probability of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. The attack requires access to the MCP task submission API, so restricting network exposure or authentication can mitigate the likelihood of exploitation."}}}}, "created": "2026-04-15T19:15:11.919224+00:00", "updated": "2026-04-17T09:00:10.964790+00:00", "vendors": ["upsonic", "upsonic$PRODUCT$upsonic"]}
