Recurring patterns

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

Auth Bypass: The project relied on the unmaintained dgrijalva/jwt-go library, which contained critical design flaws leading to potential authentication bypasses. Transitioning to actively maintained forks is required to ensure secure token validation.

Denial of Service: A critical Denial of Service vulnerability (CVE-2020-26892) affected the integrated NATS message-broker integration, allowing remote attackers to disrupt Go-Kit services using NATS transport.

Denial of Service: The Apache Thrift integration was susceptible to resource exhaustion (CVE-2020-13949), allowing remote attackers to crash Go-based Thrift RPC servers.
