Recurring patterns

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

Auth Bypass: Incomplete validation during OAuth 2.0 introspection allows attackers to bypass authentication by providing tokens with missing or unvalidated active status or issuer fields. This directly mapped to CVE-2026-11717 and CVE-2026-11718.

Auth Bypass: Multiple BigQuery execution, forecasting, and analytical tools failed to validate that requested datasets belonged to the configured dataset allowlist, allowing unauthorized data access and extraction.

SQL Injection: String formatting (fmt.Sprintf) of user-provided database identifiers, metric parameters, and connection properties allowed injection of malicious SQL commands or connection parameter modifications.
