CVE-2025-31565 identifies a Blind SQL Injection vulnerability in the WPSmartContracts plugin for WordPress, developed by Lisandro Martinez. This vulnerability stems from improper neutralization of special characters in SQL commands, allowing attackers to inject arbitrary SQL code into database queries. Blind SQL Injection means that while attackers cannot see the direct output of their injected queries, they can infer data through timing or boolean-based techniques. The affected versions include all releases up to and including 2.0.12. The vulnerability could be exploited remotely without authentication, potentially enabling attackers to extract sensitive information such as user credentials, contract data, or other confidential information stored in the database. Additionally, attackers might manipulate or delete data, impacting data integrity and availability. No patches or fixes have been published yet, and no known exploits have been detected in the wild. The plugin’s role in managing smart contracts within WordPress sites makes this vulnerability particularly concerning for organizations leveraging blockchain or contract automation technologies. The absence of a CVSS score necessitates an expert severity assessment based on the nature of the vulnerability and its potential impact.

The impact of this vulnerability is significant for organizations using the WPSmartContracts plugin. Successful exploitation could lead to unauthorized disclosure of sensitive contract and user data, undermining confidentiality. Data integrity could be compromised through unauthorized modifications or deletions of contract records or other database entries. Availability could also be affected if attackers disrupt database operations or cause application errors. Given that WordPress powers a large portion of websites globally, including many e-commerce and blockchain-related sites, the scope of affected systems could be broad. Organizations relying on WPSmartContracts for smart contract management face risks of financial loss, reputational damage, and regulatory non-compliance if sensitive data is exposed or manipulated. The lack of authentication requirement lowers the barrier to exploitation, increasing the threat level. Although no exploits are currently known in the wild, the vulnerability’s presence in a widely used plugin makes it a likely target for attackers once a reliable exploit is developed.

1. Immediately audit all WordPress sites using WPSmartContracts and identify affected versions (<= 2.0.12). 2. Restrict access to the plugin’s functionalities by limiting user roles and permissions to trusted administrators only. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the plugin’s endpoints. 4. Monitor database logs and application logs for unusual queries or error patterns indicative of SQL injection attempts. 5. Disable or remove the WPSmartContracts plugin temporarily if it is not critical to operations until a security patch is released. 6. Follow the vendor’s updates closely and apply patches immediately once available. 7. Implement database user accounts with least privilege, ensuring the WordPress database user has only necessary permissions to limit damage from injection attacks. 8. Conduct security testing, including penetration testing focused on SQL injection vectors, to verify the effectiveness of mitigations. 9. Educate site administrators about the risks and signs of SQL injection attacks to improve early detection.
