CVE-2025-65889: n/a
CVE-2025-65889 is a high-severity vulnerability in the flow. dstack() component of OneFlow v0. 9. 0, caused by a type validation flaw. This flaw allows unauthenticated remote attackers to trigger a Denial of Service (DoS) by submitting specially crafted inputs, leading to resource exhaustion or application crashes. The vulnerability does not impact confidentiality or integrity but severely affects availability. No known exploits are currently reported in the wild, and no patches have been published yet. European organizations using OneFlow, particularly in AI and machine learning workloads, should be aware of this risk. Mitigation involves monitoring for unusual application behavior, restricting access to vulnerable services, and preparing to apply vendor patches once available. Countries with significant AI research and technology sectors, such as Germany, France, and the UK, are more likely to be affected.
AI Analysis
Technical Summary
CVE-2025-65889 identifies a type validation vulnerability in the flow.dstack() function of OneFlow version 0.9.0, a popular open-source machine learning framework. The flaw arises because the function does not properly validate the types of inputs it processes, which can be exploited by attackers to cause a Denial of Service (DoS) condition. Specifically, by crafting malicious inputs that exploit this type validation weakness, an attacker can cause the application to consume excessive resources or crash, thereby disrupting service availability. The vulnerability has a CVSS v3.1 base score of 7.5, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), but high impact on availability (A:H). No known exploits have been reported in the wild, and no patches are currently available, which suggests that organizations must rely on mitigation strategies until a fix is released. The vulnerability is classified under CWE-400, which relates to uncontrolled resource consumption, a common cause of DoS attacks. Given OneFlow's role in AI and machine learning pipelines, disruption could affect critical data processing and model training tasks.
Potential Impact
For European organizations, the primary impact of CVE-2025-65889 is the potential disruption of AI and machine learning services that rely on OneFlow. This can lead to downtime, loss of productivity, and delays in data processing or model deployment. Industries such as automotive, finance, healthcare, and research institutions that use AI frameworks extensively may experience operational interruptions. The denial of service could also affect cloud-based AI services hosted in Europe, impacting service availability for end-users. While confidentiality and integrity are not directly compromised, the availability impact can have cascading effects on business continuity and service-level agreements. Additionally, the lack of patches increases the window of exposure, requiring organizations to implement compensating controls. The threat is more pronounced in countries with advanced AI ecosystems and significant adoption of OneFlow or similar frameworks.
Mitigation Recommendations
To mitigate CVE-2025-65889, European organizations should first identify and inventory all instances of OneFlow v0.9.0 in their environments. Network-level controls such as firewalls and intrusion prevention systems should be configured to restrict access to services running OneFlow, limiting exposure to untrusted networks. Application-level monitoring should be enhanced to detect abnormal resource usage or crashes related to flow.dstack() operations. Implementing rate limiting and input validation proxies can help reduce the risk of crafted input exploitation. Organizations should engage with the OneFlow development community or vendors to track patch releases and apply updates promptly once available. In the interim, consider isolating vulnerable components within segmented network zones to contain potential DoS impacts. Additionally, maintaining robust incident response plans focused on availability incidents will help minimize downtime if exploitation occurs.
