CVE-2025-11740 identifies a SQL Injection vulnerability in the wpForo Forum plugin for WordPress, specifically within the Subscriptions Manager component. The root cause is insufficient escaping of user-supplied input and the absence of prepared SQL statements, allowing attackers to append arbitrary SQL commands to existing queries. This flaw affects all versions up to and including 2.4.9. An attacker with at least Subscriber-level privileges can exploit this vulnerability without requiring additional user interaction, making it a relatively low-barrier attack vector. The injection can be used to extract sensitive information from the backend database, compromising confidentiality. The CVSS 3.1 score of 6.5 reflects a network attack vector with low complexity, requiring privileges but no user interaction, and impacting confidentiality only. No known exploits have been observed in the wild, but the vulnerability's presence in a popular WordPress plugin used for forum management increases its attractiveness to attackers. The lack of patch links suggests a fix may be pending or not yet publicly released, emphasizing the need for immediate mitigation. The vulnerability is classified under CWE-89, highlighting improper neutralization of special elements in SQL commands, a common and critical web application security issue.

For European organizations, this vulnerability poses a significant risk to the confidentiality of data stored in WordPress sites using the wpForo Forum plugin. Forums often contain sensitive user information, including personal data and private communications, which if extracted, could lead to privacy violations under GDPR and reputational damage. The ability for relatively low-privileged users to exploit this flaw increases the threat surface, especially in environments with many registered users. Exploitation could also facilitate further attacks by revealing database schema or credentials. Given the widespread use of WordPress and the popularity of forum plugins in community engagement and customer support, the impact spans multiple sectors including education, government, and private enterprises. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly once the vulnerability is public. The medium severity rating suggests that while the vulnerability is serious, it does not directly affect system integrity or availability, limiting the scope of damage to data confidentiality.

European organizations should implement the following specific mitigations: 1) Immediately audit user roles and restrict Subscriber-level privileges to trusted users only, minimizing the pool of potential attackers. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the Subscriptions Manager endpoints. 3) Monitor database query logs for anomalous or unexpected queries that could indicate exploitation attempts. 4) Until an official patch is released, consider disabling or limiting the use of the Subscriptions Manager feature if feasible. 5) Regularly update the wpForo Forum plugin as soon as a security patch becomes available from the vendor. 6) Conduct security awareness training for administrators to recognize signs of exploitation and enforce strong password policies to reduce account compromise risk. 7) Implement database user permissions with least privilege to limit the impact of any successful injection. These steps go beyond generic advice by focusing on role management, monitoring, and temporary feature restrictions tailored to this vulnerability's specifics.
