Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Cached connection states for remote MCP servers were shared across different user sessions without verifying credentials, leading to cross-user privilege leakage and unauthorized tool execution.
Auth Bypass: SSO role mapping and registration hooks failed to enforce strict-mode mapping validation or allowed domains under certain conditions, enabling unauthorized sign-ups and stale privilege persistence.
Path Traversal: FileStore local storage operations lacked strict realpath validation and canonical prefix verification, permitting local directory traversals and file escapes.
