88%of all CVEs are less likely

Readycheck to confirm it

The plugin does not properly sanitise and escape a parameter before using it in a SQL statement, leading to a SQL injection exploitable by high-privilege users such as admins.

Impact

Authenticated high-privilege attackers (admin) can exploit SQL injection through the table_id parameter in the copy_table action to extract database contents, potentially stealing user credentials and compromising the WordPress database.

Fix

Update AP Pricing Tables Lite plugin to a version newer than 1.1.6 that uses parameterized queries or prepared statements for the table_id parameter in admin-ajax.php.

How to confirm it

Send: POST /wp-login.php ; GET /wp-admin/admin.php?page=ap-pricing-tables-lite&message=1 ; @timeout: 20s
Positive when: duration_3>=5 and status_code_3 == 200 and contains(body_3, "Security check") and contains(body_2, "ap-pricing-tables-lite")
