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 in the SQL command, specifically via the event_category parameter. This parameter is insufficiently escaped and the SQL query is not properly prepared, allowing attackers with authenticated access at Subscriber-level or higher to append arbitrary SQL queries. This can lead to unauthorized data extraction from the backend database, compromising confidentiality, integrity, and availability of the affected system. The vulnerability is remotely exploitable over the network without requiring user interaction beyond authentication, making it highly dangerous. The CVSS v3.1 base score of 9.8 reflects the critical nature of this flaw, with metrics indicating network attack vector, low attack complexity, no privileges required beyond subscriber access, and no user interaction needed. Although no known exploits are currently in the wild, the vulnerability’s characteristics suggest it could be weaponized quickly. The plugin’s popularity within WordPress ecosystems means many websites could be at risk, especially if they have not updated to a patched version or implemented compensating controls. The root cause is a classic CWE-89 SQL Injection due to failure to properly sanitize and prepare SQL statements, highlighting the importance of parameterized queries and input validation in plugin development.

The impact of CVE-2025-10587 is severe for organizations using the Community Events WordPress plugin. Successful exploitation allows attackers to extract sensitive information from the database, including user data, credentials, or other confidential content. This can lead to data breaches, loss of customer trust, regulatory penalties, and reputational damage. Additionally, attackers could modify or delete data, causing integrity and availability issues, potentially disrupting business operations. Since the vulnerability requires only subscriber-level authentication, it lowers the barrier for exploitation, increasing risk from insider threats or compromised low-privilege accounts. The widespread use of WordPress and the plugin means a large attack surface globally. Organizations relying on this plugin for event management may face targeted attacks aiming to leverage this vulnerability for further network infiltration or lateral movement. The critical CVSS score underscores the urgency and potential for significant operational and financial consequences if left unmitigated.

To mitigate CVE-2025-10587, organizations should immediately update the Community Events plugin to a version that addresses this vulnerability once available. In the absence of an official patch, implement the following practical measures: restrict Subscriber-level user permissions to only trusted individuals and review existing user roles to minimize unnecessary access; employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the event_category parameter; enable detailed logging and monitor for anomalous SQL query patterns or unexpected database errors; consider temporarily disabling the plugin if it is not critical to operations; conduct a thorough code review to identify and replace vulnerable SQL query constructions with parameterized prepared statements; and educate developers and administrators on secure coding practices to prevent similar injection flaws. Regular backups and incident response plans should be in place to recover quickly if exploitation occurs. Finally, maintain awareness of updates from the plugin vendor and security advisories to apply patches promptly.
