Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The Model Context Protocol (MCP) and agent control plane implementations allowed unauthenticated sessions and bypassed user permission prompts before executing sensitive filesystem operations or command execution.
Command Injection: Untrusted caller inputs such as model names, volume configurations, and tool names were directly passed to system commands without proper shell-quoting or escaping, allowing remote code execution via subagents.
Denial of Service: Unsafe raw byte-index slicing on strings containing multi-byte UTF-8 characters caused panics when processing or truncating user-controlled inputs.
