CVE-2025-65896 identifies a SQL injection vulnerability in the long2ice assyncmy library, specifically affecting versions up to 0.2.10. The vulnerability arises from improper handling of dictionary keys that are used in SQL queries without adequate sanitization or parameterization. Attackers can exploit this flaw by crafting malicious dictionary keys that inject arbitrary SQL commands into the backend database. This can result in unauthorized data retrieval, modification, or deletion, compromising the confidentiality, integrity, and availability of the affected systems. The vulnerability was reserved on November 18, 2025, and published on December 2, 2025, but no CVSS score or patches have been released yet. There are no known exploits in the wild at this time. The lack of a CVSS score suggests that the vulnerability is newly disclosed and may not yet be fully assessed or mitigated. The attack vector involves direct manipulation of input data structures, which typically does not require authentication or user interaction if the vulnerable component is exposed to untrusted input. This makes exploitation relatively straightforward in environments where the library is used to process external data. The vulnerability is particularly relevant for applications relying on the assyncmy library for asynchronous database interactions, commonly found in Python-based web services and applications.

For European organizations, exploitation of this SQL injection vulnerability could lead to significant data breaches, unauthorized access to sensitive information, and potential data loss or corruption. Organizations handling personal data under GDPR may face regulatory penalties if such breaches occur. The integrity of critical business data could be compromised, affecting operational continuity and trust. Since the vulnerability allows arbitrary SQL command execution, attackers could escalate their privileges within the database or pivot to other parts of the network. The absence of known exploits currently reduces immediate risk, but the potential impact remains high if attackers develop exploit code. Industries such as finance, healthcare, and government services in Europe, which rely heavily on data confidentiality and integrity, are particularly at risk. Additionally, organizations using Python-based asynchronous frameworks that incorporate the assyncmy library are more exposed. The vulnerability could also affect cloud-hosted services and SaaS providers operating in Europe that use this library, potentially impacting a wide range of customers.

European organizations should immediately audit their software dependencies to identify usage of the long2ice assyncmy library, especially versions up to 0.2.10. Until an official patch is released, developers should implement strict input validation and sanitization on all dictionary keys or inputs that interact with SQL queries. Employing parameterized queries or prepared statements can prevent SQL injection regardless of input content. Monitoring database logs for unusual or unexpected queries can help detect exploitation attempts early. Organizations should also consider isolating database access and applying the principle of least privilege to limit potential damage. Engaging with the library maintainers or community to track patch releases and applying updates promptly is critical. Security teams should update their intrusion detection and prevention systems to recognize patterns indicative of this vulnerability. Conducting penetration testing focused on SQL injection vectors in affected applications can help identify exposure. Finally, organizations should review their incident response plans to prepare for potential exploitation scenarios.
