Bitdefender published the most alarming MCP security metric to date: 53% of open-source MCP server implementations rely on insecure static credentials while only 8.5% use OAuth. The report identifies five risk categories: opt-in (not default) security, supply chain poisoning, over-permissioned tokens/confused deputy, injection attacks, and absent audit logging. Two specific CVEs cited: CVE-2025-6514 (CVSS 9.6 RCE in mcp-remote) and CVE-2025-32711 ("EchoLeak" silent data exfiltration via Microsoft 365 Copilot). Builder takeaway: Audit your MCP servers TODAY. Replace static credentials with OAuth. Bitdefender
