Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Insecure credential resolution logic allowed attackers to bypass authentication and retrieve OAuth access tokens for other users by providing arbitrary identifiers. This was publicly registered under CVE-2026-3432.

Sandbox Escape: The application historically relied on insecure standard Node.js vm modules for executing user-defined code, which allowed untrusted scripts to escape constraints. These tasks were migrated to 'isolated-vm' processes running inside dedicated child subprocesses to enforce strict boundaries.

Server-Side Request Forgery: Unvalidated user-supplied URLs passed through image proxies and connector endpoints allowed attackers to initiate unauthorized requests targeting internal resources, loopback addresses, and metadata services (CVE-2025-9805, CVE-2025-10096).
