SCA: security update for neuro-cortex-memory (GHSA-gvpp-v77h-5w8g)

high Tenable Cloud Security Plugin ID 444201

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The Cortex MCP server (`neuro-cortex-memory`), a cross-platform persistent memory MCP, prior to version
3.17.1 treats the `CLAUDE_PROJECT_DIR` environment variable — automatically set by Claude Code to the
currently open project directory — as a trusted Cortex developer checkout. When the `open_visualization`
tool is invoked, `_find_dev_source()` resolves the user's active project directory as a candidate Cortex
source root. The only validation performed by `_is_cortex_root()` is a check for the presence of an
`mcp_server/` subdirectory and a `ui/unified-viz.html` file. An attacker who places these two marker files
in a malicious repository can cause Cortex to execute an arbitrary
`mcp_server/server/visualize_bootstrap.py` from that directory via `subprocess.run([sys.executable,
...])`, achieving code execution with the privileges of the victim's local user process. Version 3.17.1
fixes the issue. (CVE-2026-49986)

Solution

Update the neuro-cortex-memory library and its related packages to version 3.18.0 or later.
