Security researchers have uncovered critical vulnerabilities in the Model Context Protocol (MCP) sampling feature that enable malicious servers to execute stealthy prompt injection attacks, drain computational resources, and compromise large language model applications without user detection. The findings reveal three primary attack vectors that exploit the protocol’s inherent trust model and lack of robust security […] The post Malicious MCP Servers Enable Stealthy Prompt Injection to Drain System Resources appeared first on GBHackers Security | #1 Globally Trusted Cyber Security News Platform.
