CVE-2025-11177: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in tbenyon External Login
The External Login plugin for WordPress is vulnerable to SQL Injection via the 'log' parameter in all versions up to, and including, 1.11.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database when a PostgreSQL or MSSQL database is configured as the external authentication database.
AI Analysis
Technical Summary
The External Login WordPress plugin suffers from an SQL Injection vulnerability (CWE-89) via the 'log' parameter due to improper neutralization of special elements in SQL commands. This allows unauthenticated attackers to append malicious SQL queries to existing ones, potentially extracting sensitive data when PostgreSQL or MSSQL databases are used for external authentication. The vulnerability affects all plugin versions up to 1.11.2. The CVSS 3.1 base score is 7.5 (High), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high confidentiality impact without integrity or availability impact. No patch or official fix is currently documented.
Potential Impact
Successful exploitation enables unauthenticated attackers to extract sensitive information from the database used for external authentication when PostgreSQL or MSSQL is configured. The vulnerability does not impact data integrity or availability but poses a significant confidentiality risk. No known active exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider disabling the External Login plugin or restricting access to the vulnerable functionality. Avoid using PostgreSQL or MSSQL as external authentication databases with this plugin if possible. Monitor for updates from the vendor or security community regarding patches or workarounds.
