CVE-2025-67962 is an SQL Injection vulnerability identified in the Broken Link Checker plugin by the AIOSEO Plugin Team, affecting versions up to 1.2.6. The vulnerability stems from improper neutralization of special elements in SQL commands, which allows an attacker to inject malicious SQL code. The CVSS 3.1 score is 7.6 (high), reflecting network attack vector (remote exploitation), low attack complexity, requiring low privileges but no user interaction, and resulting in high confidentiality impact with limited integrity and availability impact. The vulnerability enables an attacker with authenticated access (low privileges) to execute arbitrary SQL commands, potentially leading to unauthorized data access or leakage. Although no known exploits are reported in the wild, the vulnerability poses a significant risk to WordPress sites using this plugin. The plugin is commonly used to detect broken links on websites, and exploitation could compromise the underlying database, exposing sensitive information or enabling further attacks. The vulnerability was published on December 16, 2025, and no official patches or mitigations have been released yet. The vulnerability's technical details indicate that the issue is due to insufficient input sanitization or parameterization in SQL queries within the plugin's codebase.

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive data stored in WordPress databases, including user information, business data, or intellectual property. The high confidentiality impact is particularly concerning for organizations subject to GDPR and other data protection regulations, as data breaches could result in regulatory penalties and reputational damage. The vulnerability requires low privileges but no user interaction, increasing the risk of exploitation by insiders or attackers who have gained limited access. The availability and integrity impacts are limited but could still disrupt website functionality or data accuracy. Organizations relying on the Broken Link Checker plugin for website maintenance may face operational disruptions if exploited. Given the widespread use of WordPress in Europe, especially among SMEs and public sector entities, the threat surface is significant. Additionally, attackers could leverage this vulnerability as a foothold for further lateral movement or privilege escalation within compromised environments.

1. Monitor official AIOSEO Plugin Team channels and security advisories for the release of patches addressing CVE-2025-67962 and apply updates immediately upon availability. 2. Until patches are released, restrict access to the WordPress admin interface and plugin management to trusted users only, minimizing the risk of exploitation by low-privilege attackers. 3. Implement Web Application Firewalls (WAF) with custom rules to detect and block SQL injection patterns targeting the Broken Link Checker plugin endpoints. 4. Conduct code reviews and, if feasible, apply temporary input validation or parameterization fixes to the plugin's SQL queries to mitigate injection risks. 5. Regularly audit database access logs and monitor for unusual query patterns or spikes in database errors that may indicate exploitation attempts. 6. Employ the principle of least privilege for WordPress users and database accounts to limit the potential impact of a successful injection attack. 7. Educate site administrators about the risks of SQL injection and the importance of timely patching and access control. 8. Consider isolating critical WordPress instances or using containerization to limit the blast radius of potential compromises.
