CVE-2026-15445 cleverplugins CVE debrief

Who should care

Administrators and users with high privileges on WordPress installations using the SEO Booster plugin should be aware of this vulnerability and take immediate action to protect their sites.

Technical summary

The vulnerability exists in the SEO Booster plugin for WordPress, specifically in the handling of the 'orderby' parameter. Despite the application of esc_sql() and sanitize_text_field(), these functions do not neutralize SQL keywords, commas, parentheses, or subquery syntax in an unquoted ORDER BY context. This allows authenticated attackers with administrator-level access and above to append additional SQL queries into existing queries, enabling them to extract sensitive information from the database.

Defensive priority

High

Recommended defensive actions

• Update the SEO Booster plugin to a version that fixes the SQL injection vulnerability.
• Limit access to the plugin's settings and functionality to only trusted users.
• Monitor database activity for suspicious queries.
• Consider implementing a web application firewall (WAF) to detect and prevent SQL injection attacks.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
