Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Connections with expired authorization status were previously released back to the pool and reused, allowing subsequent unauthorized queries to bypass credentials validation. Developers must ensure that authorization state transitions actively close and invalidate pooled connections.
Insecure TLS: Insecure handling of high-trust URI schemes failed to enforce hostname verification by default for system CA-signed certificates, exposing client traffic to Man-in-the-Middle (MitM) attacks.
Broken Cryptography: An insecure default configuration allowed 'TrustAllCertificates' and disabled hostname verification. Centralizing secure defaults that reject arbitrary untrusted certs by default is vital to prevent transport degradation.
