Breaking Darknet CAPTCHAs with General Purpose LLM

Our work evaluates the effectiveness of automated methods for solving CAPTCHA challenges commonly encountered in darknet environments. These CAPTCHAs are typically designed to operate without JavaScript, resulting in distinct characteristics compared to mainstream CAPTCHA systems. Our study...

Security Bulletin: Langflow is affected by security vulnerabilities in Model Context Protocol features

Summary Langflow uses Model Context Protocol MCP features to manage external server connections, project access, file resources, and local client integration. Weaknesses in MCP command and configuration validation, authentication and authorization enforcement, file resource handling, and request...

AEGIS: Preventing Cross-Domain Resource Abuse in MCP

The Model Context Protocol MCP is an open source JSON-RPC protocol that standardizes how large language models LLMs interact with external systems through programmatic functions known as tools. Attackers or malicious agents can exploit certain modalities of these MCP tools to degrade the overall...

Firefox DevTools MCP Model Context Protocol server for automating Firefox via WebDriver BiDi through Selenium WebDriver. Works with Claude Code, Claude Desktop, Cursor, Cline and other MCP clients. Repository: https://github.com/mozilla/firefox-devtools-mcp Note : This MCP server requires a local...

When Agents Act on Web3: An Attack-Surface Survey of MCP, Skills, and Tool Calling

AI agents increasingly act rather than merely read: across the Model Context Protocol MCP ecosystem, the share of deployed tools that modify external state has risen from 27% to 65% of tool use. When agents exercise this authority on public blockchains through MCP, skills, and tool calling, the...

Malicious MCP Servers Can Split Instructions to Make AI Coding Agents Exfiltrate Secrets

A malicious tool server connected to an AI coding assistant can quietly walk off with SSH keys, environment secrets, source code, and customer data without ever sending one obviously harmful instruction. The trick can work even after a blunt version of the same theft is refused: split the request...

CVE-2026-48039

Meta Ads MCP is a Model Context Protocol MCP server that lets AI assistants run Meta Ads. Prior to version 1.0.109, AuthInjectionMiddleware.dispatch at httpauthintegration.py:272 unconditionally forwards unauthenticated Streamable HTTP requests to downstream MCP tool handlers without issuing a 40...

CVE-2026-48039

CVE-2026-48039 : In Meta Ads MCP, versions before 1.0.109 suffer an authentication bypass where AuthInjectionMiddleware.dispatch() forwards unauthenticated /mcp requests to tool handlers, and when no per-request credential exists, falls back to META_ACCESS_TOKEN. The downstream Graph API error pa...

CVE-2026-70639

llama.cpp builds b1886 through b7445 contain a null pointer dereference vulnerability in the LLaMA-Android JNI wrapper where the bench1model function fails to validate the model context pointer before dereferencing it. Attackers can supply a malicious, corrupt, or truncated model file to trigger ...

EUVD-2026-53684

FrontMCP is a TypeScript-first framework for the Model Context Protocol MCP. Prior to 1.5.7, the sandboxed codecall:execute tool exposes live host Zod schema instances to the script via getTool, and because Zod v4 defines zod as a non-configurable, non-writable own property, the ECMAScript Proxy...
