Re-check both advisories for changed version ranges, deployment requirements and extension fixes. CVE-2026-61647 affects `@roomi-fields/notebooklm-mcp >= 1.6.0, < 2.0.3`. Its batch export functionality allowed writes outside the intended vault. Version `2.0.3` adds containment, but only when `NOTEBOOKLM_VAULT_ROOT` is configured; leaving it unset preserves unrestricted destination selection. [Notebook server advisory](https://github.com/roomi-fields/notebooklm-mcp/security/advisories/GHSA-jjhp-8crj-mppq).\n\nRed Hat separately identifies CVE-2026-44192 as indirect prompt injection leading to path traversal in the Ansible Lightspeed MCP server. Its statement concerns the VS Code extension and says the vulnerable code is absent from shipped Ansible Automation Platform artifacts. It rates the issue Moderate, but provides no affected or fixed extension-version range in the reviewed advisory.
