What this means

The Paystack WooCommerce Payment Gateway plugin for WordPress, versions up to 5.8.5, exposes sensitive customer information via the 'key' parameter on the order-pay endpoint. Unauthenticated attackers can extract this information by enumerating order IDs, but only if the custom metadata feature is enabled.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

The Paystack WooCommerce Payment Gateway plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.8.5 via the 'key' parameter. This makes it possible for unauthenticated attackers to extract customer PII — including billing name, email address, phone number, billing address, shipping address, and purchased product list — embedded into page HTML via wp_localize_script by enumerating sequential order IDs. This is only exploitable when the merchant has enabled the optional custom metadata feature in the Paystack gateway settings.
