Mitigation checklist
Recommended fix / mitigation
- If PDF processing is required, implement processing timeouts and resource constraints (CPU/memory limits) to contain the impact of infinite loops. Running pypdf workloads in containerized processes with enforced resource limits provides defense-in-depth. Upgrading to pypdf >= 6.13.1 resolves this issue.
