Detailsinfo

A vulnerability, which was classified as problematic, was found in cleverplugins SEO Booster Plugin up to 7.3.1. This affects an unknown code block of the component SQL Query Handler. The manipulation of the argument orderby with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The SEO Booster plugin for WordPress is vulnerable to time-based SQL Injection via the 'orderby' parameter in all versions up to, and including, 7.3.1 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. Although esc_sql() and sanitize_text_field() are applied, neither neutralizes SQL keywords, commas, parentheses, or subquery syntax in an unquoted ORDER BY context, leaving the clause fully attacker-controlled.

The advisory is shared at wordfence.com. This vulnerability is uniquely identified as CVE-2026-15445 since 07/10/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. The exploitation needs additional levels of successful authentication. Technical details are known, but no exploit is available.
