CVE-2025-28953 is an SQL Injection vulnerability found in the axiomthemes smart SEO WordPress plugin, affecting all versions up to and including 4.0. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker to inject malicious SQL code. The CVSS 3.1 score of 8.5 reflects a high severity, with an attack vector over the network (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality is high (C:H), as attackers can extract sensitive data from the database. Integrity impact is low (I:L), indicating limited ability to modify data, and availability is not affected (A:N). Although no public exploits are currently known, the vulnerability's characteristics make it a prime target for attackers seeking to compromise WordPress sites using this plugin. The vulnerability was reserved in March 2025 and published in November 2025, indicating recent discovery and disclosure. The lack of available patches at the time of reporting increases the urgency for interim mitigations. The vulnerability primarily threatens the confidentiality of stored data, including potentially sensitive SEO configurations and user information managed by the plugin.

For European organizations, the impact of CVE-2025-28953 can be significant, especially for those relying on WordPress sites with the smart SEO plugin for digital marketing and content management. Successful exploitation could lead to unauthorized disclosure of sensitive data such as SEO strategies, user credentials, or other database contents, potentially resulting in reputational damage, regulatory compliance violations (e.g., GDPR), and competitive disadvantage. The integrity impact, while lower, still poses risks of data tampering that could mislead SEO analytics or website behavior. Since the attack requires only low privileges and no user interaction, attackers could automate exploitation attempts, increasing the risk of widespread compromise. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score and ease of exploitation suggest rapid weaponization is likely. Organizations with limited patch management capabilities or those using outdated plugin versions are particularly vulnerable.

1. Monitor axiomthemes official channels for security patches addressing CVE-2025-28953 and apply them immediately upon release. 2. Until patches are available, implement strict input validation and sanitization on all user-supplied data interacting with the smart SEO plugin, focusing on SQL query parameters. 3. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection payloads targeting WordPress plugins. 4. Limit the privileges of accounts interacting with the database to the minimum necessary, reducing the impact of potential exploitation. 5. Conduct regular security audits and vulnerability scans on WordPress environments to identify outdated or vulnerable plugins. 6. Consider temporarily disabling or replacing the smart SEO plugin if patching is not immediately feasible. 7. Educate web administrators and developers about the risks of SQL injection and secure coding practices to prevent similar vulnerabilities.
