CVE-2026-75149 (GCVE-0-2026-75149)

Vulnerability from cvelistv5 – Published: 2026-08-19 17:48 – Updated: 2026-08-21 19:41 X_Open Source

Title

marimo < 0.23.15 Code Injection via MCP Server Configuration

Summary

marimo before 0.23.15 contains a code injection vulnerability in the notebook configuration handler that allows attackers to execute arbitrary commands by supplying a crafted MCP server entry with an attacker-controlled command value embedded in a notebook. When the notebook is opened in edit mode, marimo launches the specified command as a local subprocess before any notebook cell is executed, requiring no authentication or cell execution to trigger the vulnerability.

Severity
