Overview
A critical SQL Injection vulnerability, identified as CVE-2025-12646, has been discovered in the Community Events plugin for WordPress. This flaw affects all versions up to and including 1.5.4. Unauthenticated attackers can exploit this vulnerability to inject malicious SQL code, potentially leading to sensitive data extraction from the WordPress database.
Technical Details
The vulnerability stems from insufficient escaping of the 'dayofyear' parameter. User-supplied input for this parameter is not properly sanitized, and the existing SQL query lacks sufficient preparation. This allows attackers to append arbitrary SQL queries to the original query. By crafting malicious input for the dayofyear parameter, an attacker can potentially:
- Extract user credentials (usernames, passwords)
- Access other sensitive information stored in the database
- Modify database records
- Potentially gain complete control over the WordPress site
CVSS Analysis
The vulnerability has been assigned a CVSS score of 7.5, indicating a HIGH severity. This score reflects the potential for significant impact and the relatively low skill required to exploit the vulnerability.
- CVSS Score: 7.5 (HIGH)
Possible Impact
The exploitation of this SQL Injection vulnerability could have severe consequences for affected WordPress websites:
- Data Breach: Sensitive information, including user credentials and personal data, could be stolen.
- Website Defacement: Attackers could modify website content, causing reputational damage.
- Malware Injection: Malicious code could be injected into the website, infecting visitors.
- Complete Site Compromise: Attackers could gain full administrative control of the WordPress site.
Mitigation and Patch Steps
The vulnerability has been patched in a later version of the Community Events plugin. It is strongly recommended that all users of the Community Events plugin update to the latest version as soon as possible.
- Update the Plugin: Navigate to the “Plugins” section in your WordPress dashboard and update the Community Events plugin to the latest available version.
