3.11.5
CVE-2025-39481 describes a critical SQL Injection vulnerability discovered in the Eventer WordPress plugin. This flaw allows attackers to perform blind SQL injection, potentially leading to unauthorized data access and compromise of the WordPress site. Versions of Eventer from 0.0.0 through 3.11.4 are affected. A patch has been released in version 3.11.4.
The SQL Injection vulnerability in Eventer allows an attacker to bypass security measures and directly interact with the database underlying the WordPress site. Because it's a blind SQL injection, the attacker doesn't receive direct output from the database queries, but can infer information through timing attacks or other methods. This can be used to extract sensitive data such as user credentials, configuration details, and potentially even the entire database content. Successful exploitation could lead to complete website takeover, data breaches, and reputational damage. The blind nature of the injection makes detection more challenging, as it doesn't generate obvious error messages.
CVE-2025-39481 was publicly disclosed on 2025-05-16. The CVSS score of 9.3 (CRITICAL) indicates a high probability of exploitation. While no public proof-of-concept (PoC) code has been released at the time of writing, the severity of the vulnerability and the ease of exploitation (blind SQL injection) suggest that it is likely to become a target for malicious actors. Monitor security advisories and threat intelligence feeds for any indications of active exploitation campaigns.
Websites utilizing the Eventer plugin, particularly those running older versions (0.0.0–3.11.4), are at significant risk. Shared hosting environments where multiple websites share the same database are especially vulnerable, as a successful attack on one site could potentially compromise others. WordPress sites with weak database user permissions are also at increased risk.

The primary mitigation for CVE-2025-39481 is to immediately upgrade the Eventer plugin to version 3.11.4 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider implementing a Web Application Firewall (WAF) rule to filter potentially malicious SQL injection attempts targeting the vulnerable endpoints. Specifically, look for unusual characters or patterns in user input that are commonly associated with SQL injection attacks. Additionally, review and restrict database user privileges to minimize the impact of a successful attack. After upgrading, confirm the vulnerability is resolved by attempting a test SQL injection payload on the affected endpoint and verifying that it is properly sanitized.
Actualice el plugin Eventer a una versión superior a 3.11.4 para mitigar la vulnerabilidad de inyección SQL ciega. Verifique las actualizaciones disponibles en el repositorio de WordPress o en el sitio web del desarrollador. Implemente medidas de seguridad adicionales, como la validación y el saneamiento de las entradas del usuario, para prevenir futuras vulnerabilidades.
