PYSEC-2026-3481 MCP Python SDK: Experimental task handlers allow any client to access and cancel other clients' tasks

Summary In affected versions, the default request handlers installed by the experimental tasks feature server.experimental.enabletasks did not check which session created a task before acting on it. On a server with more than one connected client, any client could observe, read results from, and...

Safety and Security: Experimental Validation of Encrypted Model Predictive Control

In this paper, we revisit the problem of an encrypted model predictive control MPC design, representing a significant challenge in the recent field of secure process control. Existing methods in secure optimization-based control are non-existent and even partial implementation fails to address th...
