Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-400

Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.

addresses: CWE-400

Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.

addresses: CWE-400

Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.

addresses: CWE-400

Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.

addresses: CWE-400

Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.

addresses: CWE-400

Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.

addresses: CWE-400

The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.

addresses: CWE-400

Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.

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).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

A type validation flaw in the flow.dstack() component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.

Deeper analysisAI

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.
