CVE-2025-10586 is a critical SQL Injection vulnerability identified in the Community Events plugin for WordPress, developed by jackdewey. The flaw exists in all versions up to and including 1.5.1, where the 'event_venue' parameter is insufficiently sanitized before being incorporated into SQL queries. Specifically, the plugin fails to properly escape or prepare the user-supplied input, allowing authenticated users with Subscriber-level privileges or higher to append arbitrary SQL commands to existing queries. This improper neutralization of special elements (CWE-89) enables attackers to perform unauthorized database operations such as extracting sensitive data, modifying records, or deleting information. The vulnerability is remotely exploitable over the network without requiring additional user interaction, and no elevated privileges beyond Subscriber access are necessary. The CVSS v3.1 base score of 9.8 reflects the critical nature of this vulnerability, with high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers, especially given the popularity of WordPress and its plugins. The lack of available patches at the time of disclosure increases the urgency for organizations to implement interim mitigations or monitor for suspicious activity.

For European organizations, exploitation of this vulnerability could lead to significant data breaches, including exposure of sensitive customer or internal data stored in WordPress databases. The ability to modify or delete database content could disrupt business operations, damage reputations, and lead to regulatory non-compliance under GDPR and other data protection laws. Public-facing websites using the Community Events plugin are particularly vulnerable, potentially allowing attackers to pivot into broader network compromises. The critical severity and ease of exploitation mean that even low-privileged users can cause substantial harm, increasing the risk profile for organizations relying on this plugin. The impact extends to service availability, as malicious SQL commands could corrupt or delete essential data, causing downtime and loss of business continuity.

European organizations should immediately audit their WordPress installations to identify the presence of the Community Events plugin and its version. Until an official patch is released, it is advisable to disable or remove the plugin to eliminate the attack surface. If removal is not feasible, restrict Subscriber-level user capabilities to prevent unauthorized access to the vulnerable parameter. Implement Web Application Firewalls (WAF) with custom rules to detect and block SQL injection patterns targeting the 'event_venue' parameter. Regularly monitor database logs and web server logs for suspicious queries or anomalous behavior indicative of exploitation attempts. Additionally, enforce strict input validation and sanitization at the application level where possible. Organizations should also prepare for rapid patch deployment once a fix becomes available and conduct thorough post-patch testing to ensure remediation.
