RCE Vulnerability in Anthropic's MCP STDIO Implementation
OX Security disclosed a systemic RCE design flaw in Anthropic's Model Context Protocol STDIO transport layer, not a patchable bug but an architectural weakness propagating across 150M+ downloads, 30+ coordinated disclosures, and 10+ CVEs spanning downstream IDEs, frameworks, and registries. Security engineers and DevOps teams embedding MCP into agentic pipelines should treat this as critical infrastructure risk requiring immediate architectural review.
