In the Langflow vulnerability, attackers log in as an ordinary non-admin user, add an MCP server whose command field contains a malicious payload, the server accepts and stores the command without validation, and code execution is then triggered by fetching the MCP server list; captured payloads include extracting environment variables, reading /etc/passwd and probing with commands such as id and whoami.

UnverifiedA single compromised MCP server can execute prompt injection, credential exfiltration, delivery of phishing toolkit fingerprints, PII leakage, token theft via OAuth, and SSRF attacks.80% similarUnverifiedPrompt injection is a security vulnerability unique to LLM applications, where attackers can embed malicious instructions in tool results returned by an MCP server to manipulate agent behavior.78% similarUnverifiedDisclosed MCP vulnerabilities include: argocd-mcp shipped with no authentication at all, Rill's OAuth flow allowed attackers to skip the user consent step, and prompt injection existed in the tool descriptions of multiple MCP servers.77% similarUnverifiedIn AI agent scenarios, over-privileged MCP servers can become a springboard for attackers to conduct lateral movement or data exfiltration when subjected to prompt injection attacks.76% similarUnverifiedThe arXiv study "My Credentials, Please" systematically defines and quantifies the "filesystem capability laundering" problem in MCP servers: attackers manipulate tool parameters to make tools declared as non-filesystem tools read host files outside their declared scope.75% similar
