Unauthenticated SQL injection via pre-HMAC callback query
Published Aug 14, 2026 · Updated Aug 14, 2026
SQL injection in Paymob for WooCommerce before 4.1.9 allows remote attackers to read arbitrary database data via the payment callback. The public callback inserts a client-supplied pixel identifier into an SQL query before checking the provider HMAC signature, enabling reflected and time-based blind extraction. No authentication or valid signature is required, and the reported impact is database confidentiality, including stored credentials and secrets, not modification or service interruption.
