CVE-2025-11501 is an SQL Injection vulnerability identified in the 'Dynamically Display Posts' WordPress plugin developed by markomaksym. This vulnerability exists in all versions up to and including 1.1. The root cause is insufficient escaping and lack of proper preparation of the 'tax_query' parameter within SQL queries. Specifically, user-supplied input in this parameter is not adequately sanitized, allowing attackers to append arbitrary SQL commands to the existing queries. Because the vulnerability is exploitable without authentication or user interaction, an unauthenticated attacker can remotely execute malicious SQL code against the WordPress site's database. The primary impact is unauthorized disclosure of sensitive information stored in the database, such as user credentials, personal data, or site configuration details. The vulnerability does not affect data integrity or availability directly but compromises confidentiality significantly. The CVSS 3.1 score of 7.5 reflects a network attack vector with low complexity, no privileges required, and no user interaction needed. Although no known exploits have been reported in the wild yet, the vulnerability's characteristics make it a prime candidate for exploitation. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability is classified under CWE-89, which covers improper neutralization of special elements in SQL commands, a common and critical web application security flaw.

For European organizations, this vulnerability poses a significant risk of data breaches through unauthorized access to sensitive database information. Organizations running WordPress sites with the affected plugin may have confidential customer data, intellectual property, or internal configurations exposed. This can lead to regulatory non-compliance, especially under GDPR, resulting in legal penalties and reputational damage. The ease of exploitation without authentication increases the attack surface, allowing attackers to target multiple sites indiscriminately. Industries such as e-commerce, finance, healthcare, and government agencies in Europe that rely on WordPress for content management are particularly vulnerable. The potential for data exfiltration could facilitate further attacks, including identity theft, phishing, or lateral movement within networks. Although availability and integrity are not directly impacted, the confidentiality breach alone is critical. The absence of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high.

European organizations should immediately audit their WordPress installations to identify the presence of the 'Dynamically Display Posts' plugin, especially versions up to 1.1. Since no official patch is currently available, organizations should consider temporarily disabling or removing the plugin to eliminate the attack vector. Implementing a Web Application Firewall (WAF) with SQL Injection detection and prevention rules can help block malicious payloads targeting the 'tax_query' parameter. Input validation and sanitization should be enforced at the application level, ensuring that any user-supplied parameters are properly escaped or parameterized in SQL queries. Monitoring database logs and web server access logs for unusual query patterns or repeated failed attempts can provide early detection of exploitation attempts. Organizations should also maintain regular backups of their WordPress sites and databases to enable recovery in case of compromise. Finally, staying informed about updates from the plugin developer and applying patches promptly once available is essential for long-term security.
