CVE-2026-30625: n/a
Upsonic version 0. 71. 6 contains a critical remote code execution vulnerability in its MCP server/task creation functionality. The vulnerability arises because users can define MCP tasks with arbitrary command and argument values. Although an allowlist restricts commands, some allowed commands like npm and npx accept argument flags that enable execution of arbitrary OS commands. This can lead to remote code execution with the privileges of the Upsonic process. Version 0. 72. 0 introduced a warning about the risks of using Stdio servers that can execute commands directly on the host machine. No official patch or remediation has been confirmed yet.
AI Analysis
Technical Summary
CVE-2026-30625 affects Upsonic 0.71.6 and involves a remote code execution vulnerability in the MCP server/task creation feature. The application permits users to specify commands and arguments for MCP tasks. Despite an allowlist, certain allowed commands (npm, npx) accept flags that can be exploited to run arbitrary OS commands. This flaw allows attackers to execute code remotely with the same privileges as the Upsonic process. A warning was added in version 0.72.0 regarding the use of Stdio servers that can execute commands directly, but no official fix or patch is documented.
Potential Impact
Successful exploitation of this vulnerability allows an attacker to execute arbitrary operating system commands remotely with the privileges of the Upsonic process. This can lead to full compromise of the affected system, including confidentiality, integrity, and availability impacts. The CVSS score of 9.8 reflects the critical severity and ease of exploitation without privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Version 0.72.0 added a warning about the risks of using Stdio servers but does not constitute a fix. Until an official patch is released, avoid using vulnerable Upsonic versions or restrict access to the MCP server/task creation functionality to trusted users only.
