CVE-2026-28115: WP Attractive Donations SQLi Vulnerability

CVE-2026-28115 Overview

CVE-2026-28115 is a critical SQL Injection vulnerability affecting the WP Attractive Donations System plugin for WordPress. This plugin, developed by loopus, provides donation functionality through Stripe and PayPal integrations. The vulnerability allows unauthenticated attackers to perform Blind SQL Injection attacks against WordPress sites using vulnerable versions of the plugin.

The improper neutralization of special elements used in SQL commands (CWE-89) enables malicious actors to manipulate database queries, potentially leading to unauthorized data extraction from the WordPress database, including sensitive donor information and administrative credentials.

Critical Impact

Unauthenticated attackers can exploit this Blind SQL Injection vulnerability to extract sensitive database contents including user credentials, payment information, and other confidential data from WordPress sites running WP Attractive Donations System version 1.25 or earlier.

Affected Products

• WP Attractive Donations System - Easy Stripe & Paypal donations plugin versions through 1.25
• WordPress installations using WP_AttractiveDonationsSystem plugin
• Sites accepting donations via the affected plugin's Stripe and PayPal integrations

Technical Details for CVE-2026-28115

Vulnerability Analysis

This SQL Injection vulnerability exists due to improper input validation and sanitization within the WP Attractive Donations System plugin. The plugin fails to properly neutralize user-supplied input before incorporating it into SQL queries, creating an injection point that attackers can exploit without authentication.

The Blind SQL Injection nature of this vulnerability means that while direct database output is not returned to the attacker, they can infer information through time-based or boolean-based techniques. This makes the attack stealthier but equally dangerous, as patient attackers can systematically extract entire database contents character by character.

The network-accessible attack vector with no authentication requirements makes this vulnerability particularly dangerous for internet-facing WordPress installations. Successful exploitation could compromise not only donation data but the entire WordPress database, including administrator accounts and potentially other sensitive plugin data.

Root Cause

The root cause of CVE-2026-28115 is the failure to implement proper input sanitization and parameterized queries within the WP Attractive Donations System plugin. User-controlled input is directly concatenated into SQL query strings without adequate escaping or use of prepared statements, which is a fundamental security anti-pattern that violates secure coding practices for database interactions.

WordPress provides secure database abstraction methods through the $wpdb->prepare() function specifically designed to prevent SQL injection. The vulnerable code paths in WP_AttractiveDonationsSystem bypass these protections by constructing raw SQL queries with unsanitized input parameters.

Attack Vector

The attack is network-based and requires no authentication or user interaction, making it highly accessible to remote attackers. The exploitation process involves crafting malicious input containing SQL syntax that alters the intended query logic.

Attackers leverage Blind SQL Injection techniques to extract data by observing application behavior changes based on injected conditional statements. Time-based blind injection uses database sleep functions to confirm successful injection, while boolean-based techniques rely on different application responses for true versus false conditions in injected queries.

Detection Methods for CVE-2026-28115

Indicators of Compromise

• Unusual database query patterns or errors in WordPress debug logs indicating SQL syntax issues
• HTTP requests containing SQL injection payloads targeting donation-related endpoints
• Abnormal database query execution times suggesting time-based blind SQL injection attempts
• Unexpected authentication events or privilege escalations following exploitation

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect common SQL injection patterns in request parameters
• Monitor WordPress error logs for database-related exceptions and SQL syntax errors
• Deploy database activity monitoring to identify unusual query patterns or data extraction attempts
• Analyze web server access logs for requests containing SQL injection signatures targeting the WP Attractive Donations System plugin paths

Monitoring Recommendations

• Enable detailed logging for all database queries during incident investigation periods
• Configure alerting for failed database queries or unusual query response times
• Monitor for bulk data access patterns that may indicate successful data exfiltration
• Implement real-time security monitoring through SentinelOne Singularity for endpoint and workload protection

How to Mitigate CVE-2026-28115

Immediate Actions Required

• Audit your WordPress installations to identify sites running WP Attractive Donations System plugin version 1.25 or earlier
• Consider temporarily disabling the WP Attractive Donations System plugin until a patched version is available
• Implement Web Application Firewall rules to block SQL injection attempts targeting this plugin
• Review database access logs for signs of prior exploitation attempts

Patch Information

At the time of publication, users should monitor the plugin vendor and WordPress plugin repository for security updates. The vulnerability affects WP Attractive Donations System versions through 1.25. Website administrators should:

1. Check for plugin updates regularly in the WordPress admin dashboard
2. Subscribe to security advisories from the plugin developer
3. Monitor the Patchstack Vulnerability Report for patch availability announcements

Workarounds

• Deploy a Web Application Firewall (WAF) such as Wordfence or Sucuri to filter malicious SQL injection payloads
• Restrict access to WordPress admin and plugin endpoints via IP allowlisting where feasible
• Consider using an alternative donation plugin until a security patch is released
• Implement database user privilege restrictions to limit the impact of successful SQL injection

# WordPress configuration hardening example
# Add to wp-config.php to enable debug logging for monitoring
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

# Consider adding database query logging via plugin or custom code
# to monitor for suspicious activity during the vulnerability window
