Threat actors are leveraging blind prompt injection against exposed LiteLLM gateways and Model Context Protocol (MCP) servers to achieve Remote Code Execution (RCE) on host infrastructure. By manipulating AI agents via indirect instructions, attackers bypass standard input filters to execute arbitrary code, facilitating memory credential theft. This attack chain allows for the exfiltration of API keys and cloud secrets, enabling lateral movement into production cloud environments for data exfiltration or the deployment of cryptominers. Immediate remediation requires strict input sanitization, sandboxing of agent tool-connectors, and the implementation of Zero Trust access controls for all AI gateways.
