Cybersecurity researchers have discovered a critical security vulnerability in artificial intelligence (AI) company Anthropic's Model Context Protocol ( MCP ) Inspector project that could result in remote code execution (RCE) and allow an attacker to gain complete access to the hosts. The vulnerability, tracked as CVE-2025-49596 , carries a CVSS score of 9.4 out of a maximum of 10.0. "This is one of the first critical RCEs in Anthropic's MCP ecosystem, exposing a new class of browser-based attacks against AI developer tools," Oligo Security's Avi Lumelsky said in a report published last week. "With code execution on a developer's machine, attackers can steal data, install backdoors, and move laterally across networks - highlighting serious risks for AI teams, open-source projects, and enterprise adopters relying on MCP." MCP, introduced by Anthropic in November 2024, is an open protocol that standardizes the way large language model (LLM) appli...

Cybersecurity researchers have discovered a critical vulnerability in the open-source mcp-remote project that could result in the execution of arbitrary operating system (OS) commands. The vulnerability, tracked as CVE-2025-6514 , carries a CVSS score of 9.6 out of 10.0. "The vulnerability allows attackers to trigger arbitrary OS command execution on the machine running mcp-remote when it initiates a connection to an untrusted MCP server, posing a significant risk to users – a full system compromise," Or Peles, JFrog Vulnerability Research Team Leader, said . Mcp-remote is a tool that sprang forth following Anthropic's release of Model Context Protocol (MCP), an open-source framework that standardizes the way large language model (LLM) applications integrate and share data with external data sources and services. It acts as a local proxy, enabling MCP clients like Claude Desktop to communicate with remote MCP servers, as opposed to running them locally on the same...

Security teams have spent years building identity and access controls for human users and service accounts. But a new category of actor has quietly entered most enterprise environments, and it operates entirely outside those controls. Claude Code, Anthropic's AI coding agent, is now running across engineering organizations at scale. It reads files, executes shell commands, calls external APIs, and connects to third-party integrations called MCP servers. It does all of this autonomously, with the full permissions of the developer who launched it, on the developer's local machine, before any network-layer security tool can see it. It leaves no audit trail that the existing security infrastructure was built to capture. This walkthrough covers Ceros, an AI Trust Layer built by Beyond Identity that sits directly on the developer's machine alongside Claude Code and provides real-time visibility, runtime policy enforcement, and a cryptographic audit trail of every action the a...

A recently disclosed critical security flaw impacting nginx-ui, an open-source, web-based Nginx management tool, has come under active exploitation in the wild. The vulnerability in question is CVE-2026-33032 (CVSS score: 9.8), an authentication bypass vulnerability that enables threat actors to seize control of the Nginx service. It has been codenamed MCPwn by Pluto Security. "The nginx-ui MCP (Model Context Protocol) integration exposes two HTTP endpoints: /mcp and /mcp_message," according to an advisory released by nginx-ui maintainers last month. "While /mcp requires both IP whitelisting and authentication (AuthRequired() middleware), the /mcp_message endpoint only applies IP whitelisting -- and the default IP whitelist is empty, which the middleware treats as 'allow all.'"  "This means any network attacker can invoke all MCP tools without authentication, including restarting nginx, creating/modifying/deleting nginx configuration files, and t...

A novel attack technique named EchoLeak has been characterized as a "zero-click" artificial intelligence (AI) vulnerability that allows bad actors to exfiltrate sensitive data from Microsoft 365 (M365) Copilot's context sans any user interaction. The critical-rated vulnerability has been assigned the CVE identifier CVE-2025-32711 (CVSS score: 9.3). It requires no customer action and has been already addressed by Microsoft. There is no evidence that the shortcoming was exploited maliciously in the wild. "AI command injection in M365 Copilot allows an unauthorized attacker to disclose information over a network," the company said in an advisory released Wednesday. It has since been added to Microsoft's Patch Tuesday list for June 2025, taking the total number of fixed flaws to 68. Aim Security, which discovered and reported the issue, said it's an instance of a large language model (LLM) Scope Violation that paves the way for indirect prompt injecti...

As the field of artificial intelligence (AI) continues to evolve at a rapid pace, fresh research has found how techniques that render the Model Context Protocol ( MCP ) susceptible to prompt injection attacks could be used to develop security tooling or identify malicious tools, according to a new report from Tenable. MCP, launched by Anthropic in November 2024, is a framework designed to connect Large Language Models (LLMs) with external data sources and services, and make use of model-controlled tools to interact with those systems to enhance the accuracy, relevance, and utility of AI applications. It follows a client-server architecture, allowing hosts with MCP clients such as Claude Desktop or Cursor to communicate with different MCP servers, each of which exposes specific tools and capabilities. While the open standard offers a unified interface to access various data sources and even switch between LLM providers, they also come with a new set of risks, ranging from exc...

Cybersecurity researchers have disclosed a now-patched, high-severity security flaw in Cursor, a popular artificial intelligence (AI) code editor, that could result in remote code execution (RCE). The vulnerability, tracked as CVE-2025-54135 (CVSS score: 8.6), has been addressed in version 1.3 released on July 29, 2025. It has been codenamed CurXecute by Aim Labs, which previously disclosed EchoLeak . "Cursor runs with developer‑level privileges, and when paired with an MCP server that fetches untrusted external data, that data can redirect the agent's control flow and exploit those privileges," the Aim Labs Team said in a report shared with The Hacker News. "By feeding poisoned data to the agent via MCP, an attacker can gain full remote code execution under the user privileges, and achieve any number of things, including opportunities for ransomware, data theft, AI manipulation and hallucinations, etc." In other words, the remote code execution can trigg...

Cybersecurity researchers have disclosed details of a now-patched security flaw impacting Ask Gordon , an artificial intelligence (AI) assistant built into Docker Desktop and the Docker Command-Line Interface (CLI), that could be exploited to execute code and exfiltrate sensitive data. The critical vulnerability has been codenamed DockerDash by cybersecurity company Noma Labs. It was addressed by Docker with the release of version 4.50.0 in November 2025. "In DockerDash, a single malicious metadata label in a Docker image can be used to compromise your Docker environment through a simple three-stage attack: Gordon AI reads and interprets the malicious instruction, forwards it to the MCP [Model Context Protocol] Gateway, which then executes it through MCP tools," Sasi Levi, security research lead at Noma, said in a report shared with The Hacker News. "Every stage happens with zero validation, taking advantage of current agents and MCP Gateway architecture." ...

Cybersecurity researchers have disclosed details of a now-patched vulnerability in the popular figma-developer-mcp Model Context Protocol ( MCP ) server that could allow attackers to achieve code execution. The vulnerability, tracked as CVE-2025-53967 (CVSS score: 7.5), is a command injection bug stemming from the unsanitized use of user input, opening the door to a scenario where an attacker can send arbitrary system commands. "The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.)," according to a GitHub advisory for the flaw. "Successful exploitation can lead to remote code execution under the server process's privileges." Given that the Framelink Figma MCP server exposes various tools to perform operations in Figma using artificial intelligence (AI)-powered coding agents like Cursor, an attacker co...

Trend Micro researchers Alfredo Oliveira and David Fiser said the AI-powered data repair and photo editing application "contradicted its privacy policy by...

Cybersecurity researchers have disclosed a high-severity security flaw in the artificial intelligence (AI)-powered code editor Cursor that could result in remote code execution. The vulnerability, tracked as CVE-2025-54136 (CVSS score: 7.2), has been codenamed MCPoison by Check Point Research, owing to the fact that it exploits a quirk in the way the software handles modifications to Model Context Protocol (MCP) server configurations. "A vulnerability in Cursor AI allows an attacker to achieve remote and persistent code execution by modifying an already trusted MCP configuration file inside a shared GitHub repository or editing the file locally on the target's machine," Cursor said in an advisory released last week. "Once a collaborator accepts a harmless MCP, the attacker can silently swap it for a malicious command (e.g., calc.exe) without triggering any warning or re-prompt." MCP is an open-standard developed by Anthropic that allows large language mode...

Cybersecurity researchers have disclosed details of a new SmartLoader campaign that involves distributing a trojanized version of a Model Context Protocol ( MCP ) server associated with Oura Health to deliver an information stealer known as StealC . "The threat actors cloned a legitimate Oura MCP Server – a tool that connects AI assistants to Oura Ring health data – and built a deceptive infrastructure of fake forks and contributors to manufacture credibility," Straiker's AI Research (STAR) Labs team said in a report shared with The Hacker News. The end game is to leverage the trojanized version of the Oura MCP server to deliver the StealC infostealer, allowing the threat actors to steal credentials, browser passwords, and data from cryptocurrency wallets. SmartLoader, first highlighted by OALABS Research in early 2024, is a malware loader that's known to be distributed via fake GitHub repositories containing artificial intelligence (AI)-generated lures to giv...

Cybersecurity researchers have discovered what has been described as the first-ever instance of a malicious Model Context Protocol ( MCP ) server spotted in the wild, raising software supply chain risks. According to Koi Security, a legitimate-looking developer managed to slip in rogue code within an npm package called " postmark-mcp " that copied an official Postmark Labs library of the same name. The malicious functionality was introduced in version 1.0.16, which was released on September 17, 2025. The actual "postmark-mcp" library, available on GitHub , exposes an MCP server to allow users to send emails, access and use email templates, and track campaigns using artificial intelligence (AI) assistants. The npm package in question has since been deleted from npm by the developer " phanpak ," who uploaded it to the repository on September 15, 2025, and maintains 31 other packages. The JavaScript library attracted a total of 1,643 downloads. ...

Cybersecurity researchers have discovered a critical "by design" weakness in the Model Context Protocol's ( MCP ) architecture that could pave the way for remote code execution and have a cascading effect on the artificial intelligence (AI) supply chain. "This flaw enables Arbitrary Command Execution (RCE) on any system running a vulnerable MCP implementation, granting attackers direct access to sensitive user data, internal databases, API keys, and chat histories," OX Security researchers Moshe Siman Tov Bustan, Mustafa Naamnih, Nir Zadok, and Roni Bar said in an analysis published last week. The cybersecurity company said the systemic vulnerability is baked into Anthropic's official MCP software development kit (SDK) across any supported language, including Python, TypeScript, Java, and Rust. In all, it affects more than 7,000 publicly accessible servers and software packages totaling more than 150 million downloads. At issue are unsafe defaults in...
