CVE-2025-32306 is a high-severity SQL Injection vulnerability identified in the LambertGroup Radio Player Shoutcast & Icecast WordPress Plugin, affecting all versions up to 4.4.6. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), enabling an attacker to perform Blind SQL Injection attacks. Blind SQL Injection allows an attacker to infer database information by sending crafted queries and analyzing the application's responses, even when direct output of database errors or results is not available. The CVSS 3.1 base score of 8.5 reflects a network attack vector with low attack complexity, requiring privileges (PR:L) but no user interaction, and impacting confidentiality with high impact, while integrity remains unaffected and availability impact is low. The scope is changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable component, potentially allowing attackers to access or influence data beyond their privileges. This vulnerability is particularly critical because WordPress plugins are widely used and often have elevated privileges within the WordPress environment, which can lead to unauthorized data disclosure or further exploitation. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk if weaponized. The lack of available patches at the time of publication increases the urgency for mitigation. The plugin's use of Shoutcast and Icecast streaming services suggests it is deployed in websites offering internet radio or streaming media, which may hold user data or proprietary content.

For European organizations, this vulnerability poses a substantial risk, especially for media companies, broadcasters, and content providers using WordPress sites with the affected plugin. Exploitation could lead to unauthorized disclosure of sensitive data stored in backend databases, including user credentials, personal data, or proprietary streaming configurations. Given the GDPR regulations in Europe, any data breach involving personal data could result in significant legal and financial penalties. Additionally, the altered scope of the vulnerability means attackers might escalate privileges or access data beyond the plugin itself, potentially compromising entire WordPress installations. The availability impact is low but could still disrupt streaming services temporarily, affecting service continuity and user trust. The requirement for privileges (PR:L) suggests that attackers need some level of access, such as a registered user account, which is common in community or subscriber-based sites, making exploitation feasible. The absence of user interaction lowers the barrier for automated attacks once initial access is obtained. Overall, the vulnerability threatens confidentiality primarily, with potential cascading effects on organizational reputation and compliance posture.

1. Immediate mitigation should include restricting access to the WordPress admin and plugin management interfaces to trusted users only, minimizing the risk of privilege escalation or exploitation. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL Injection patterns targeting the plugin's endpoints. 3. Monitor logs for unusual database query patterns or repeated failed attempts that could indicate exploitation attempts. 4. Until an official patch is released, consider disabling or uninstalling the affected plugin if feasible, or replacing it with alternative plugins that provide similar functionality without known vulnerabilities. 5. Conduct a thorough audit of user privileges on WordPress sites to ensure that only necessary users have elevated permissions, reducing the attack surface. 6. Regularly back up databases and website content to enable quick recovery in case of compromise. 7. Educate site administrators about the risks of SQL Injection and the importance of applying updates promptly once patches become available. 8. Engage with the plugin vendor or community to track patch releases and apply them immediately upon availability.
