Insertion of Sensitive Information Into Sent Data vulnerability in Doofinder Doofinder for WooCommerce doofinder-for-woocommerce allows Retrieve Embedded Sensitive Data.This issue affects Doofinder for WooCommerce: from n/a through <= 2.10.13.

AnalysisAI

Doofinder for WooCommerce through version 2.10.13 discloses sensitive information by inserting it into sent data, allowing remote unauthenticated attackers to retrieve embedded secrets with low attack complexity. The vulnerability affects all installations of the plugin and has been reported by Patchstack, with EPSS exploitation probability at 0.02% (low real-world risk), though no KEV status or public exploit code has been identified.

Technical ContextAI

The vulnerability stems from CWE-201 (Insertion of Sensitive Information Into Sent Data), a data exposure flaw where the WordPress plugin for WooCommerce integration with Doofinder search service embeds sensitive credentials or tokens in network traffic or response data without proper redaction. This affects the WooCommerce plugin infrastructure (CPE: cpe:2.3:a:doofinder:doofinder_for_woocommerce:*:*:*:*:*:*:*:*) which operates as a search enhancement layer for e-commerce platforms. The root cause involves failure to sanitize or encrypt sensitive data before transmitting it to the client side or including it in HTTP responses, a common pattern in WordPress plugins that integrate third-party services.

RemediationAI

Update Doofinder for WooCommerce to version 2.10.14 or later. Users should navigate to WordPress Dashboard → Plugins → Installed Plugins, locate Doofinder for WooCommerce, and click Update if available, or manually download the patched version from the WordPress.org plugin repository. Verify the plugin version in Settings after update to confirm successful patch application. For organizations unable to update immediately, audit API keys and authentication tokens used by the plugin and rotate any credentials that may have been exposed during the vulnerability window.
