MCP Servers Enable Arbitrary Code Execution

7.9
Security researchers on Feb. 19, 2026 reported that the Model Context Protocol (MCP), designed by Anthropic and introduced in November 2024, can be exploited to execute arbitrary code and exfiltrate sensitive data from connected systems. Because MCP lets large language models interact with external tools and repositories, the flaw undermines enterprise LLM integrations and requires immediate hardening, input validation, and privilege restrictions.
Scoring Rationale
High operational risk and broad impact on LLM integrations, but single-source reporting and limited technical detail reduce confidence.
