What io.github.jurimaxam-dotcom/chemdraw-mcp does
Chat → chemical structure. An MCP server for Claude Desktop that turns molecule names or SMILES into publication-style 2D structure drawings — "draw aspirin" produces a print-ready PNG/SVG, rendered fully offline with RDKit. No ChemDraw required; ChemDraw CDXML is available as an optional extra format for users who want to keep editing there.

Playwright downloads and installs browsers without verifying the authenticity of the SSL certificate
### Summary Use of `curl` with the `-k` (or `--insecure`) flag in installer scripts allows attackers to deliver arbitrary executables via Man-in-the-Middle (MitM) attacks. This can lead to full system compromise, as the downloaded files are installed as privileged applications. ### Details The following scripts in the `microsoft/playwright` repository at commit [`bee11cbc28f24bd18e726163d0b9b1571b4f26a8`](https://github.com/microsoft/playwright/commit/bee11cbc28f24bd18e726163d0b9b1571b4f26a8) u
