Threat & Defense Details
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.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
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.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
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
Why these techniques?
CVE describes remote unauthenticated exploitation of an input validation flaw (negative/large dimensions) in a network-exposed component to trigger uncontrolled resource consumption and application DoS, directly matching T1499.004 Application or System Exploitation.
NVD Description
A dimension validation flaw in the flow.empty() component of OneFlow 0.9.0 allows attackers to cause a Denial of Service (DoS) via a negative or excessively large dimension value.
Deeper analysisAI
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.
