CVE-2026-2024 identifies a critical SQL Injection vulnerability in the PhotoStack Gallery plugin for WordPress, maintained by savitasoni. The vulnerability exists in all versions up to and including 0.4.1 due to insufficient escaping and lack of prepared statements when handling the 'postid' parameter. This parameter is directly used in SQL queries without proper sanitization, allowing attackers to append arbitrary SQL commands. The injection flaw is exploitable remotely over the network without any authentication or user interaction, making it highly accessible to attackers. Successful exploitation can lead to unauthorized extraction of sensitive data from the backend database, compromising confidentiality. The vulnerability is classified under CWE-89, which covers improper neutralization of special elements in SQL commands. Although no public exploits have been reported yet, the CVSS 3.1 base score of 7.5 reflects the high impact on confidentiality and ease of exploitation. The plugin is commonly used to display photo galleries on WordPress sites, which are prevalent across many organizations, increasing the attack surface. The lack of available patches at the time of disclosure necessitates alternative mitigation strategies. This vulnerability highlights the critical importance of input validation and the use of parameterized queries in web application development.

For European organizations, this vulnerability poses a significant risk to the confidentiality of data stored in WordPress databases using the PhotoStack Gallery plugin. Attackers can exploit the flaw to extract sensitive information such as user data, configuration details, or other protected content without authentication. This can lead to data breaches, reputational damage, and potential regulatory penalties under GDPR if personal data is exposed. Public-facing websites, especially those in sectors like media, education, and e-commerce that use photo galleries extensively, are particularly vulnerable. The ease of exploitation means attackers can automate attacks at scale, increasing the likelihood of widespread compromise. Additionally, the exposure of database contents could facilitate further attacks, such as privilege escalation or lateral movement within the network. The absence of known exploits currently provides a window for proactive defense, but the risk remains high given the vulnerability's nature and the popularity of WordPress in Europe.

Organizations should immediately assess their WordPress installations for the presence of the PhotoStack Gallery plugin and verify the version in use. Since no official patches are currently available, the most effective mitigation is to disable or uninstall the plugin until a secure update is released. Implementing a Web Application Firewall (WAF) with SQL Injection detection and prevention capabilities can help block exploitation attempts targeting the 'postid' parameter. Conduct thorough input validation and sanitization on all user-supplied data in custom code or plugins. Review and tighten database user permissions to limit the potential impact of any successful injection. Monitor web server and application logs for suspicious activity related to SQL injection attempts. Organizations should also prepare to apply patches promptly once they become available and consider isolating WordPress instances to minimize lateral movement risks. Regular security audits and penetration testing focusing on injection flaws will help identify similar vulnerabilities proactively.
