DescriptionCVE.org

An input validation vulnerability in the oneflow.index_add component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.

Executive ViewAI

Why It Matters

CVE-2025-71007 is a high-severity denial-of-service vulnerability affecting OneFlow v0.9.0 that allows attackers to crash or disable systems using malicious input. Organizations running OneFlow in production environments face service disruption risk, and the existence of public exploits elevates the threat likelihood.

Business Impact: High
Compensating Controls

Implement strict input validation and length limits on all index_add requests via WAF or API gateway; restrict network access to OneFlow instances to trusted sources only; disable or isolate the index_add functionality if not critical to operations; monitor for suspicious input patterns and DoS attack signatures; consider rate limiting and connection throttling on affected endpoints.
