CVE-2025-59288high · fixed

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

Local Playwright browser through residential proxies — agent picks country + sticky identity

README

Aethyn Browser MCP — residential-proxy browser control for AI agents (pick the country, one identity per task)

An MCP server that lets an AI agent drive a real browser through residential proxies, choosing the exit country / city, tier, and a sticky per-task session — at call time. The browser (Playwright Chromium) runs locally on your machine; you bring your own proxy credentials. Defaults to Aethyn residential proxies, and works with any HTTP proxy you configure.

The only browser MCP where the agent picks the country and holds one identity per task.

Why this exists

Playwright MCP drives a browser well, but its proxy is set once at server startup — one static exit for the whole session. The agent can't ask for a Japanese exit for one task and a German exit for the next.
Hosted "web scraping" MCPs hide the proxy and hand back JSON — no runtime control over geo or session identity, and it's their pool at their price.

This server gives the agent runtime, per-task, steerable geo + sticky identity as tools — exactly what browser agents need to pull country-specific data (pricing, SERPs, catalogs, availability) and feed it into a chart or pipeline.

Quickstart

Add the server to your MCP client — Claude Desktop (claude_desktop_config.json) or Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "aethyn-browser": {
      "command": "npx",
      "args": ["-y", "aethyn-browser-mcp"],
      "env": {
        "AETHYN_USERNAME": "aethyn-XXXXX",
        "AETHYN_PASSWORD": "your-proxy-password",
        "AETHYN_DEFAULT_TIER": "premium"
      }
    }
  }
}

Chromium is downloaded automatically on first install (~170 MB, one-time). If your environment blocks post-install scripts, run it yourself: npx playwright install chromium.

⚠️ Set the tier to match your plan. AETHYN_DEFAULT_TIER defaults to premium (port 2099). If your account is Elite, set it to elite (port 5499) — otherwise traffic hits the Premium port and the proxy returns 407 (auth rejected), even though the browser launched fine. The agent can also override per task with tier: "elite".

That's it. Ask your agent something like "Launch a browser in Japan, open example.co.jp, verify the exit IP is Japanese, and give me the page as markdown."

Tools

Tool	What it does
`aethyn_launch_browser`	Launch local Chromium through a residential exit in a chosen `country` (+ `city`/`state` on Elite), `tier`, and sticky `session`. Returns a `session_id`.
`aethyn_navigate`	Go to a URL; waits for load and returns the HTTP status, final URL, and title.
`aethyn_get_content`	Return the page cleaned for reading (`markdown` / `text` / `html`).
`aethyn_snapshot`	Accessibility snapshot (roles, names, `[ref=..]` handles) — how the agent decides what to click.
`aethyn_click`	Click by `ref` (from the snapshot) or a CSS/role/text `selector`.
`aethyn_type`	Type into an input (optionally submit with Enter).
`aethyn_check_exit_ip`	Fetch IP info through the session's proxy to verify the geo actually landed.
`aethyn_new_identity`	Rotate to a fresh exit IP (same country) and clear cookies.
`aethyn_close`	Close the session's context and free memory.
`aethyn_list_countries`	Discover available countries (and Elite cities) at runtime.
