Detailsinfo

A vulnerability classified as critical was found in edmonparker Read More & Accordion Plugin up to 3.5.7 on WordPress. This vulnerability affects the function esc_sql of the file ReadMoreData.php. The manipulation of the argument orderby with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Read More & Accordion plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'orderby' parameter in all versions up to, and including, 3.5.7. This is due to the use of esc_sql() without surrounding the value in quotes in an ORDER BY clause inside the getAllDataByLimit() and getAccordionAllDataByLimit() functions in ReadMoreData.php. The user-supplied $_GET['orderby'] value is only processed through esc_attr() (an HTML-escaping function) before being passed to these database functions, where esc_sql() is applied but the value is directly concatenated—unquoted—into the ORDER BY fragment of the SQL query before $wpdb->prepare() is called. Because esc_sql() only escapes quote characters and backslashes (which are irrelevant in an unquoted ORDER BY context), an attacker can inject arbitrary SQL expressions such as (SELECT SLEEP(5)) or conditional subqueries to perform time-based blind data extraction. This makes it possible for authenticated attackers with administrator-level access or above (or any role explicitly permitted access to the plugin's admin pages via the yrm-user-roles setting) to extract sensitive data from the database, including administrator credential hashes.

The weakness was presented by Bima Ikhsan. The advisory is available at wordfence.com. This vulnerability was named CVE-2026-7472 since 04/29/2026. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are necessary for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1505 by the MITRE ATT&CK project.
