Description

A vulnerability was identified in elgentos magento2-dev-mcp up to 1.0.2. The affected element is the function executeMagerun2Command of the file src/index.ts. Such manipulation leads to os command injection. An attack has to be approached locally. The exploit is publicly available and might be used. The name of the patch is aa1ffcc0aea1b212c69787391783af27df15ae9d. A patch should be applied to remediate this issue.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @elgentos/magento2-dev-mcp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of @elgentos/magento2-dev-mcp for GHSA-xqv9-qr76-hfq2. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
