CVE-2026-110179 Affiliate Toolkit CVE debrief

Who should care

WordPress administrators, security teams, and users with editor-level access should assess exposure and prioritize remediation for installations using the affiliate-toolkit plugin.

Why it matters

CVE-2026-110179 is a SQL injection vulnerability in the affiliate-toolkit WordPress plugin that allows users with editor-level access to read arbitrary database information. WordPress administrators and security teams should assess exposure and prioritize remediation.

• Potential data breaches due to unauthorized database access
• Elevation of privileges for users with editor-level access
• Possible disruption of WordPress site functionality
• Need for verification of affected versions and scope of vulnerability

Technical summary

The affiliate-toolkit WordPress plugin before 3.8.9 does not validate user-supplied sort values against an allowlist before using them in database queries. This vulnerability allows users with editor-level access and above to perform SQL injection attacks and read arbitrary information from the database. The affected administrative list screen requires only a lower-privilege capability rather than an administrator one, increasing the risk of exploitation. The vulnerability can be used to read sensitive information, including the super administrator's password hash, on multisite installations.

Defensive priority

Assess exposure and prioritize remediation for WordPress installations using the affiliate-toolkit plugin, especially those with users having editor-level access.

Recommended defensive actions

• Assess WordPress installations for the affiliate-toolkit plugin version before 3.8.9
• Verify user access levels and restrict editor-level access where possible
• Monitor database queries for suspicious activity
• Consider implementing a web application firewall to detect SQL injection attempts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability. Further verification is required to determine the full scope of affected versions and potential impact. The vulnerability is confirmed in versions before 3.8.9, but the extent of the vulnerability in later versions is unclear. Defenders should verify the version of the affiliate-toolkit plugin in use and review database access controls. Additionally, they should monitor database queries for suspicious activity and consider implementing a web application
