Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The connection pool historically allowed stale database sessions to persist after credential or URL changes. If old connections are not discarded, unauthorized clients can bypass updated database access controls.
Auth Bypass: WallFilter bypasses, including incorrect SPI order execution and failure to clear ThreadLocal context, can lead to data isolation bypasses and exposure of restricted database columns via proxies.
