⚠️ Action Required: If you have AgentDeskAI’s browser-tools-mcp installed in any AI agent stack, remove or disable it immediately. There is no patch. There will be no patch. The exploit is public.

A high-severity OS command injection vulnerability has been disclosed in the AgentDeskAI browser-tools-mcp package, affecting all versions through v1.2.0 — which is also the final release the project ever shipped.

CVE: CVE-2026-7064
CVSS v3.1 Score: 7.3 (High)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
CWE: CWE-77/78 (OS Command Injection)
Patch available: No. Project is unmaintained.
Exploit disclosed: Yes. Publicly available.

What’s Vulnerable

The vulnerability lives in browser-tools-server/browser-connector.ts, a file inside the MCP (Model Context Protocol) server that connects AI agents to browser automation functionality. The flaw allows an attacker to inject arbitrary OS commands through the affected code path, exploitable from remote with no authentication required and no user interaction needed.

In practical terms: if this MCP server is exposed (even locally on your developer machine), an attacker who can reach it can run arbitrary commands on your system. Given that many developers run MCP servers with broad filesystem and network access to support agent workflows, the blast radius of exploitation is potentially severe.

The Critical Context: This Project Is Dead

What makes CVE-2026-7064 especially dangerous isn’t just the CVSS score — it’s the project’s status. browser-tools-mcp reached v1.2.0 in March 2025 and has not been updated since. The maintainers were notified via GitHub issue #232 when the vulnerability was discovered, but they have not responded.

This is not a “patch is in progress” situation. The project appears archived or effectively abandoned. There is no fix coming. The vulnerability will not be remediated through the normal responsible disclosure process.

Some early coverage of this CVE incorrectly advised users to “patch immediately” — there is nothing to patch. The only correct advisory is to remove or disable the tool entirely and migrate to an alternative.

Who Is Affected

If you installed browser-tools-mcp from AgentDeskAI as part of your browser-connected AI agent workflow — including configurations with Claude Code, OpenClaw, Codex, or any MCP-compatible agent framework — you are affected. Check your installed MCP servers immediately.

To identify whether you have it installed:

# If using npm globally
npm list -g browser-tools-mcp

# Check your MCP config for any reference to browser-tools-mcp
grep -r "browser-tools-mcp" ~/.config/ ~/.*rc ~/.mcp* 2>/dev/null

If you find it, uninstall and remove all references from your MCP configuration files before restarting any agent services.

Alternatives and Migration

The browser-connected MCP tool space has alternatives. Depending on what functionality you were using browser-tools-mcp for:

  • Playwright MCP and Puppeteer MCP tools offer browser automation under actively maintained codebases
  • WebFetch skill within OpenClaw covers basic URL fetching without exposing a browser automation server
  • Remote browser services with proper sandboxing (Browserless, Browserbase) reduce local exposure

The key lesson is that MCP tools are still a nascent ecosystem with wildly varying levels of maintenance commitment. Before adding any MCP server to your agent stack, check the project’s last commit date, issue responsiveness, and whether there’s an organization or company backing it.

The Broader Signal

CVE-2026-7064 is a preview of a problem the agentic AI community will face repeatedly as the MCP ecosystem matures: tools that were useful in 2024–2025 are now abandoned but still installed in thousands of developer environments. The combination of powerful OS-level access, public exploit availability, and zero patch path makes unmaintained MCP tools a meaningful attack surface.

Audit your MCP tools now. Not next sprint. Now.
