25 Aug 2026, 8:43 PM	The Hacker News	6.0	Marimo Notebook Flaw Could Run MCP Commands Before Cells Execute in Edit Mode Marimo notebooks prior to version 0.23.15 had a code injection flaw (CVE-2026-75149, CVSS 8.7/8.8) where a crafted notebook could supply an attacker-controlled MCP server command through notebook configuration that runs as a local subprocess when the victim opens the notebook in edit mode—before any cell executes. Marimo patched this in 0.23.15 by treating notebook metadata as attacker-controlled and passing config through an allowlist, stripping the ai, mcp, completion, secrets, and server sections. Current PyPI release is 0.24.0. Why: If you or your team use Marimo notebooks, update to at least 0.23.15 immediately—opening a shared or untrusted notebook in edit mode could have silently launched arbitrary local subprocesses via MCP config. Anyone distributing Marimo notebooks for demos, tutorials, or collaboration should verify recipients are on a patched version, since the attack requires only that the victim opens the file. security marimo mcp notebooks code-injection
