Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Cross-namespace reference validation is a critical security boundary. Failing to enforce bidirectional verification or namespace selectors allows unauthorized cross-namespace tool and agent references.
Command Injection: Spawning shell commands using user-supplied inputs directly via shell execution (e.g., asyncio.create_subprocess_shell) leads to sandbox escapes and arbitrary host command execution.
Path Traversal: Failing to canonicalize paths and verify prefixes when exposing file read, write, or editing interfaces lets attackers escape designated working directories.
