- Mitigation guidance
- To mitigate implement hard caps on iterative processing loops and resource allocations per request. Apply rate limiting and set strict connection/processing timeouts to prevent a single complex operation from tying up worker threads. For this specific flaw, administrators can also configure system-level resource constraints (like CPU cgroups) for the service.
