Summary

CVE-2025-65889 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Oneflow Oneflow. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-65889 is a type validation flaw in the flow.dstack() component of OneFlow version 0.9.0. This vulnerability enables attackers to trigger a Denial of Service (DoS) condition by supplying a crafted input. It is mapped to CWE-400 (Uncontrolled Resource Consumption) and carries a CVSS v3.1 base score of 7.5, reflecting network accessibility, low attack complexity, no privileges or user interaction required, unchanged scope, and high availability impact with no effects on confidentiality or integrity.

Unauthenticated remote attackers can exploit this flaw over the network without privileges or user interaction. Exploitation involves delivering a specially crafted input to the vulnerable flow.dstack() function, resulting in resource exhaustion or service disruption that renders the affected OneFlow instance unavailable.

Mitigation details and patches are referenced in vendor resources, including the OneFlow website at http://oneflow.com, the GitHub repositories https://github.com/Daisy2ang and https://github.com/Oneflow-Inc/oneflow, and the specific issue tracker at https://github.com/Oneflow-Inc/oneflow/issues/10663. Security practitioners should consult these for updates, workarounds, or fixed versions beyond v0.9.0.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Remote unauthenticated crafted input to public-facing OneFlow component directly enables application exploitation for endpoint DoS via resource exhaustion (CWE-400).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

SI-10 directly enforces input validation mechanisms to prevent type validation flaws like the one in flow.dstack() from being exploited with crafted inputs.

prevent

SC-5 provides denial-of-service protection to limit the effects of resource exhaustion attacks triggered by malformed inputs to the vulnerable component.

prevent

SI-2 ensures timely flaw remediation through patching or updating OneFlow to versions beyond v0.9.0 that address the type validation vulnerability.
