Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sandbox Escape: Execution of untrusted Playwright/Node.js script monitors repeatedly allowed breakout vectors into the host environment due to unblocked browser object context leakage, prompting major migrations from vm2 and node:vm to isolated architectures.
Auth Bypass: Tenant boundaries and Single Sign-On (SSO) flows suffered bypasses where missing signature verification, incorrect project context mapping, or relying on client-supplied headers allowed unauthorized cross-project database manipulation.
SQL Injection: User-controlled telemetry parameters and database column names were dynamically concatenated inside ClickHouse queries instead of using schema verification or parameterized execution context, allowing arbitrary database inspection.
