CVE-2025-10586 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, stemming from improper neutralization of special elements in the 'event_venue' parameter. Specifically, the plugin fails to sufficiently escape or prepare SQL queries that incorporate this user-supplied input. As a result, authenticated users with as low as Subscriber-level privileges can append arbitrary SQL commands to existing queries. This can enable attackers to extract sensitive information from the underlying database, such as user credentials, personal data, or site configuration details. The vulnerability does not require elevated privileges beyond Subscriber, nor does it require user interaction beyond normal use of the plugin. The CVSS v3.1 score of 9.8 reflects the vulnerability's ease of exploitation (network vector, low attack complexity), lack of required privileges, and the critical impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk to WordPress sites using this plugin, especially those exposing event management functionality to authenticated users. The lack of available patches at the time of disclosure increases the urgency for mitigation. The vulnerability is classified under CWE-89, which denotes improper neutralization of special elements used in SQL commands, a common and dangerous injection flaw.

For European organizations, this vulnerability poses a severe risk to the confidentiality, integrity, and availability of WordPress-based websites utilizing the Community Events plugin. Exploitation could lead to unauthorized disclosure of sensitive customer or employee data, including personal identifiable information (PII), violating GDPR and other data protection regulations. The integrity of website content and backend data could be compromised, potentially allowing attackers to manipulate event information or inject malicious content. Availability could also be impacted if attackers execute destructive SQL commands, leading to denial of service or site defacement. Organizations relying on WordPress for event management, especially public-facing or customer-interactive portals, face reputational damage and potential regulatory penalties if exploited. The ease of exploitation by low-privilege authenticated users increases the threat surface, as even minimally trusted users or compromised accounts could be leveraged to launch attacks. This vulnerability also raises concerns for managed service providers hosting WordPress sites for multiple clients across Europe, amplifying the potential impact.

European organizations should immediately audit their WordPress installations to identify the presence of the Community Events plugin and verify the version in use. Until an official patch is released, the following mitigations are recommended: 1) Restrict Subscriber and higher user roles from accessing or interacting with the vulnerable 'event_venue' parameter or related event management features. 2) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'event_venue' parameter. 3) Employ database query monitoring to identify anomalous or unauthorized SQL commands. 4) Enforce strict input validation and sanitization at the application level, potentially by customizing the plugin code to use prepared statements or parameterized queries. 5) Limit the number of users with Subscriber or higher privileges and enforce strong authentication controls to reduce the risk of account compromise. 6) Monitor logs for suspicious activity related to event management functions. 7) Plan for rapid deployment of patches once available from the vendor. 8) Consider temporarily disabling the plugin if it is not critical to business operations. These steps help reduce the attack surface and mitigate exploitation risk until a secure version is released.
