CVE-2025-65896 identifies a severe SQL injection vulnerability in the long2ice assyncmy library, specifically affecting versions up to 0.2.10. The vulnerability arises because the library improperly handles crafted dictionary keys, which are used to construct SQL queries without adequate sanitization or parameterization. This flaw allows attackers to inject arbitrary SQL commands remotely without authentication or user interaction, leading to potential full compromise of the underlying database. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), a common and dangerous injection flaw. The CVSS v3.1 base score of 9.8 reflects the ease of exploitation (network vector, low attack complexity), no privileges required, and the high impact on confidentiality, integrity, and availability of the affected systems. Although no patches or fixes have been published yet, the vulnerability's public disclosure means attackers could develop exploits rapidly. Organizations using this library in their backend services or applications that interact with SQL databases are at risk of data breaches, unauthorized data manipulation, or denial of service. The lack of known exploits in the wild currently provides a small window for proactive defense.

For European organizations, the impact of this vulnerability could be severe. Exploitation could lead to unauthorized access to sensitive data, including personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Integrity of data could be compromised, affecting business operations, financial records, and customer trust. Availability of services relying on the affected library could be disrupted, causing operational downtime and financial loss. Sectors such as finance, healthcare, government, and e-commerce, which commonly use SQL databases and open-source libraries, are particularly vulnerable. The critical nature of the vulnerability means that even organizations with mature security postures must urgently assess their exposure. Additionally, the absence of patches increases the risk window, potentially inviting targeted attacks or automated exploitation campaigns. The impact extends beyond direct victims to their customers and partners, amplifying the threat landscape within Europe.

Given the absence of official patches, European organizations should immediately audit their use of the long2ice assyncmy library and identify affected versions. Temporary mitigations include implementing strict input validation and sanitization on all inputs that could influence dictionary keys used in SQL queries. Employing parameterized queries or prepared statements can prevent SQL injection by separating code from data. Network-level protections such as web application firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting this vulnerability. Monitoring database logs for unusual queries or access patterns can provide early detection of exploitation attempts. Organizations should also engage with their software vendors or development teams to prioritize upgrading or replacing the vulnerable library once patches become available. Additionally, conducting security awareness training for developers on secure coding practices related to SQL injection can reduce future risks. Finally, maintaining regular backups and incident response plans will help mitigate damage if exploitation occurs.
