CVE-2026-10688Public exploitNetwork attack vector

Authenticated code execution via unsandboxed Python exec

Published Jun 2, 2026 · Updated Jun 2, 2026

Code injection in Siddharth Ahuja Blender MCP allows remote authenticated users to execute arbitrary Python code through an MCP tool. The execute_blender_code function forwards its code argument to the Blender add-on, whose execute_code handler passes it directly to Python exec() without validation or sandboxing. An MCP client able to invoke the tool can run operating-system commands with the Blender process's privileges.
