CVE-2025-15268: Infility Global WordPress SQL Injection

CVE-2025-15268 Overview

The Infility Global plugin for WordPress contains an unauthenticated SQL Injection vulnerability in the infility_get_data API action. This security flaw affects all versions up to and including 2.14.46, allowing remote attackers to manipulate database queries without any authentication requirements. The vulnerability stems from insufficient escaping of user-supplied parameters combined with inadequate preparation of existing SQL queries.

Critical Impact

Unauthenticated attackers can extract sensitive information from the WordPress database, potentially compromising user credentials, personal data, and other confidential information stored within the application.

Affected Products

• Infility Global WordPress Plugin versions up to and including 2.14.46
• WordPress installations with vulnerable Infility Global plugin configurations
• Servers with specific configurations that allow SQL query appending

Technical Details for CVE-2025-15268

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists within the Infility Global WordPress plugin's API handler. The infility_get_data action processes user input without proper sanitization or parameterized query preparation. When an attacker submits crafted input through this API endpoint, the malicious SQL statements are concatenated directly into the existing database queries.

The vulnerability is particularly dangerous because it requires no authentication, meaning any remote attacker with network access to the WordPress installation can attempt exploitation. Under certain server configurations, attackers can append additional SQL queries to extract sensitive database contents, including user tables, configuration data, and potentially password hashes.

Root Cause

The root cause lies in the plugin's failure to implement proper input validation and parameterized queries. The affected code in the db.class.php and str.class.php files does not adequately escape user-supplied parameters before incorporating them into SQL statements. Additionally, the main plugin file infility_global.php handles the API action without sufficient security controls, allowing the injection point to be reached by unauthenticated users.

Attack Vector

The attack vector is network-based, requiring no privileges or user interaction. Attackers can craft malicious HTTP requests to the WordPress REST API or AJAX endpoints that trigger the vulnerable infility_get_data action. The injected SQL payloads are appended to legitimate queries, enabling data extraction through techniques such as UNION-based injection, blind SQL injection, or time-based extraction methods depending on the server configuration.

The vulnerability mechanism involves insufficient input sanitization in the API parameter handling. When processing requests to the infility_get_data action, user-supplied data flows directly into database queries without proper escaping or prepared statement usage. For detailed technical analysis of the vulnerable code paths, refer to the WordPress Plugin Code Review and the Wordfence Vulnerability Report.

Detection Methods for CVE-2025-15268

Indicators of Compromise

• Unusual or malformed requests to WordPress API endpoints containing SQL syntax characters such as single quotes, UNION statements, or comment sequences
• Database query logs showing unexpected SQL statements appended to legitimate Infility Global plugin queries
• Access logs revealing repeated requests to infility_get_data endpoints with varying payloads indicative of injection attempts
• Unexpected data exfiltration patterns or database read operations from non-administrative sources

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in requests targeting the Infility Global plugin
• Enable WordPress database query logging to capture and analyze queries originating from the vulnerable API action
• Implement intrusion detection signatures for SQL injection attack patterns targeting WordPress plugins
• Monitor for requests containing typical SQL injection payloads including UNION SELECT, OR 1=1, and comment markers

Monitoring Recommendations

• Configure real-time alerting for suspicious database query patterns associated with the Infility Global plugin
• Review web server access logs regularly for anomalous API request patterns
• Implement SentinelOne Singularity platform to detect exploitation attempts through behavioral analysis and threat intelligence integration
• Enable verbose logging on WordPress installations to capture detailed request information for forensic analysis

How to Mitigate CVE-2025-15268

Immediate Actions Required

• Update the Infility Global plugin to a patched version that addresses the SQL injection vulnerability immediately
• If an update is not available, temporarily disable or remove the Infility Global plugin until a security patch is released
• Conduct a security audit of WordPress database contents to identify potential data exposure
• Review web server logs for evidence of prior exploitation attempts

Patch Information

Organizations should monitor the official WordPress plugin repository and the Wordfence Vulnerability Report for patch availability. Update the Infility Global plugin to the latest version once a security fix is released. Verify that the patched version includes proper input sanitization and parameterized query implementation for the infility_get_data action.

Workarounds

• Implement WAF rules to block requests containing SQL injection patterns targeting the infility_get_data endpoint
• Restrict network access to WordPress administrative and API endpoints using IP allowlisting where feasible
• Disable the Infility Global plugin entirely if it is not critical to site functionality until a patch is available
• Consider implementing additional security plugins that provide request filtering and SQL injection protection

# Configuration example - Block suspicious requests at web server level
# Apache mod_rewrite rule to block common SQL injection patterns
RewriteEngine On
RewriteCond %{QUERY_STRING} (union.*select|select.*from|insert.*into|drop.*table) [NC]
RewriteRule ^(.*)$ - [F,L]
