CVE-2026-12743 in affiliate-toolkit Plugin
Summary
by MITRE • 08/14/2026
The affiliate-toolkit – Multi-Network Affiliate & Amazon Product Display plugin for WordPress is vulnerable to time-based SQL Injection via the 'orderby' parameter in all versions up to, and including, 3.8.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

This vulnerability exists within the affiliate-toolkit plugin for WordPress, specifically affecting versions up to and including 3.8.8. The issue manifests as a time-based sql injection flaw that occurs when processing the 'orderby' parameter in multi-network affiliate and amazon product display functionality. The root cause stems from inadequate input sanitization where user-supplied parameters are not properly escaped before being incorporated into database queries. This weakness allows attackers to manipulate the sql execution flow by introducing malicious sql code through the orderby parameter.
The vulnerability is particularly dangerous because it requires only administrator-level access or higher, making it accessible to authenticated attackers who already have elevated privileges within the wordpress environment. Once exploited, this vulnerability enables attackers to append additional sql queries to existing database operations, creating a pathway for unauthorized data extraction from the underlying database system. The time-based nature of the injection means that attackers can infer information from the database by measuring response times, making the exploitation more stealthy and effective.
From a cybersecurity perspective, this vulnerability maps directly to common weakness enumerations such as CWE-89 sql injection and CWE-778 insufficient logging, while also aligning with attack techniques documented in the attack tactics and techniques framework where adversaries attempt to escalate privileges through database manipulation. The impact extends beyond simple data theft as it provides attackers with potential access to sensitive user information, configuration details, and potentially other system credentials stored within the same database infrastructure.
Organizations using this plugin should immediately implement mitigations including updating to the latest version of the affiliate-toolkit plugin where the vulnerability has been patched, implementing proper input validation and parameterized queries for all user-supplied parameters, and conducting thorough security audits of their wordpress installations. Additionally, network segmentation and privilege management should be reviewed to ensure that administrative access is properly restricted and monitored. The vulnerability demonstrates the critical importance of proper input sanitization in web applications and highlights how even authenticated attackers with elevated privileges can cause significant damage through sql injection attacks.
