CVE-2025-10587 is a critical SQL Injection vulnerability identified in the Community Events plugin for WordPress, developed by jackdewey. The vulnerability exists in all versions up to and including 1.5.1 and stems from improper neutralization of special elements within the event_category parameter. Specifically, the plugin fails to adequately escape user-supplied input and does not use parameterized queries or prepared statements, which allows attackers to append arbitrary SQL commands to existing queries. This flaw can be exploited by any authenticated user with Subscriber-level access or higher, which is a relatively low privilege level in WordPress. The attacker can remotely inject malicious SQL code that can extract sensitive information from the backend database, such as user credentials, personal data, or other confidential content. The vulnerability affects the confidentiality, integrity, and availability of the affected systems. The CVSS 3.1 base score of 9.8 indicates a critical severity, with an attack vector that is network-based, requiring no user interaction, and no elevated privileges beyond subscriber access. Although no known exploits are currently in the wild, the ease of exploitation and the potential impact make this a high-priority issue. The lack of available patches at the time of publication necessitates immediate risk mitigation strategies. This vulnerability is particularly dangerous because it leverages a common plugin used in WordPress event management, which is widely deployed across various sectors including public-facing websites and community portals.

For European organizations, the impact of CVE-2025-10587 can be severe. Organizations relying on the Community Events plugin for managing public or internal events may face data breaches exposing sensitive user information, including personal data protected under GDPR. The SQL Injection can lead to unauthorized data disclosure, data manipulation, or even complete database compromise, potentially disrupting business operations and damaging reputation. Attackers could leverage this vulnerability to escalate privileges, pivot within the network, or deploy further attacks such as ransomware. The critical nature of the vulnerability means that even low-privilege users can cause significant harm, increasing the attack surface. Public sector organizations, educational institutions, and event management companies in Europe that use WordPress extensively are particularly at risk. The breach of personal data could result in regulatory penalties and loss of customer trust. Additionally, the availability of event services could be impacted, affecting organizational workflows and public engagement.

Immediate mitigation steps include restricting Subscriber-level user capabilities to the minimum necessary, especially limiting access to event_category parameters or event management features. Administrators should audit user roles and permissions to ensure no unnecessary privileges are granted. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the event_category parameter. Monitor database logs and application logs for unusual query patterns or spikes in database errors. Until an official patch is released, consider disabling or removing the Community Events plugin if feasible, or replacing it with a more secure alternative. Regularly update WordPress core and all plugins to the latest versions once patches become available. Employ database-level protections such as limiting database user permissions to only what is necessary for the plugin's operation. Conduct security awareness training for administrators to recognize signs of exploitation. Finally, prepare incident response plans to quickly address any detected compromise related to this vulnerability.
