From MCP to Shell: MCP Auth Flaws Enable RCE in Claude Code, Gemini CLI and More

Security vulnerabilities are a constant threat to the digital world. In recent times, researchers have identified multiple critical flaws in various software applications that can compromise user data and grant unauthorized access to malicious actors. One such application is Claude Code, which has recently been found to be vulnerable to Remote Code Execution (RCE) due to an authentication flaw.

For those unfamiliar with MCP, it stands for Microsoft's Connected Platform, a set of tools designed to simplify the development process for developers building connected experiences. However, the recent discovery of security vulnerabilities in its authentication system has left many wondering if their applications are at risk.

Gemini CLI is another popular tool that has been affected by the same vulnerability. Gemini CLI is an open-source command-line interface that provides a simple and intuitive way to interact with Git repositories. Despite its ease of use, its security has recently come under scrutiny due to the widespread adoption of MCP in various development environments.

But what exactly does this mean for users? In short, if you're using applications built on top of MCP or Gemini CLI, you could be at risk of a security breach. RCE vulnerabilities can allow malicious actors to inject code into your system, potentially leading to data theft, system compromise, and even physical harm.

Fortunately, researchers have been working tirelessly to identify and address these vulnerabilities. By developing secure protocols and implementing robust authentication systems, developers can ensure that their applications remain protected from cyber threats.
