CVE-2026-8705
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk39th percentile — higher than 39% of all known CVEs
Summary
The ClearSale Total plugin for WordPress is vulnerable to SQL Injection via the `pagseguro[metodo]` POST parameter of the `clearsale_total_push` AJAX action in all versions up to and including 3.4.2. Although a `wp_verify_nonce()` check exists, the failing branch's `die()` is commented out, allowing the vulnerability to be exploited.
Risk Assessment
Unauthenticated attackers can inject additional SQL queries, leading to the leakage of sensitive information from the database. Exploitation requires the target server to be running PHP < 8.0.
Recommendation
It is recommended to update the plugin to the latest version and ensure the server is running PHP version 8.0 or higher. Additionally, consider implementing further security measures for unauthenticated users.
Original NVD description (English source)
The ClearSale Total plugin for WordPress is vulnerable to SQL Injection via the `pagseguro[metodo]` POST parameter of the `clearsale_total_push` AJAX action in all versions up to, and including, 3.4.2. The handler is registered for unauthenticated users (`wp_ajax_nopriv_clearsale_total_push`), and although a `wp_verify_nonce()` check exists, the failing branch's `die()` is commented out so execution continues regardless of nonce validity. On PHP < 8.0 the attacker-supplied `$metodo` value bypasses the `switch ($metodo) { case 4: ... }` guard via loose type juggling (the string `"4 AND SLEEP(5)"` compares equal to integer `4`), reaching an unquoted `UPDATE wp_cs_total_dadosextras SET metodo=$metodo, ...` query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the target server to be running PHP < 8.0.
