Name of the Vulnerable Software and Affected Versions: Ajax Load More WordPress plugin versions prior to 5.3.2

Description: The issue concerns unvalidated input in the Ajax Load More WordPress plugin, leading to SQL Injection. This occurs in the POST /wp-admin/admin-ajax.php endpoint with the repeater parameter, specifically when set to ' or sleep(5)# and type set to test.

Recommendations: For versions prior to 5.3.2, update to version 5.3.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the /wp-admin/admin-ajax.php endpoint until the update is applied. Avoid using the repeater parameter in the affected API endpoint until the issue is resolved.
