CVE-2026-100149
WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons <= 4.7.3 - Unauthenticated Sensitive Information Disclosure via HMAC Signature Collision (Missing Domain Separation) in HMAC Signature Domain-Separation Flaw in `/yamidoo/v1/customer`…
Description
The WPZOOM Connect: AI Chat, Click to Chat, Social Icons & Share Buttons plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.7.3 via the 'x-yamidoo-signature (attacker-obtained via inline_js identify payload)' parameter. This makes it possible for unauthenticated attackers to extract the full customer card — including name, WordPress user ID, order history, order totals, purchased products, payment method labels, and EDD Software Licensing license keys with status and activation counts — for any arbitrary victim email address on the site. Exploitation requires the attacker to register a WooCommerce customer or subscriber-level account with a crafted email address whose local part encodes the target timestamp and victim email, allowing the signature printed into the page HTML by inline_js() to pass verify_request() for an arbitrary victim; both the share_customer_data and identify_logged_in settings are enabled by default, so no non-default configuration is required.
