Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Query cancellation mechanisms are highly prone to race conditions, leaks, and unreleased native memory. Cancelled execution fragments and uninitialized Apache Arrow memory buffers can bypass cleanup handles, leading to continuous CPU/memory consumption and JVM crashes.
Path Traversal: Path resolution mechanisms for local configuration files and spill directories can escape intended directory boundaries via relative paths or symbolic links, enabling arbitrary directory traversal or deletion.
Auth Bypass: Improper parsing of multi-source queries containing comma-separated index lists can cause fine-grained access control (FGAC) evaluations to skip checks, resulting in unauthorized data access.
