Summary

CVE-2025-65888 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 Application or System Exploitation (T1499.004); 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-2025-65888 is a dimension validation flaw in the flow.empty() component of OneFlow version 0.9.0. This vulnerability enables attackers to cause a Denial of Service (DoS) by supplying a negative or excessively large dimension value, leading to uncontrolled resource consumption as classified under CWE-400. The issue carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and was published on 2026-01-28.

Remote attackers require no authentication or privileges and can exploit this over the network with low attack complexity and no user interaction. Exploitation triggers a high-impact availability disruption, such as crashing the OneFlow process or rendering it unresponsive, without affecting confidentiality or integrity.

Advisories and potential patches are detailed in references including the OneFlow website at http://oneflow.com, the project repository at https://github.com/Oneflow-Inc/oneflow, and a specific issue tracker entry at https://github.com/Oneflow-Inc/oneflow/issues/10664. Security practitioners should consult these for mitigation guidance and updates.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates the dimension validation flaw by requiring validation of inputs to reject negative or excessively large dimension values before processing in flow.empty().

SC-5 Denial-of-service Protection good match
prevent

Protects against the DoS caused by uncontrolled resource consumption from invalid dimension inputs via denial-of-service protections.

SI-2 Flaw Remediation good match
prevent

Remediates the specific flaw in OneFlow 0.9.0's flow.empty() component through timely patching to eliminate the vulnerability.
