# CVE-2026-103379: WATI Chat and Notification <= 1.1.8 - Unauthenticated Customer Order PII Disclosure via Leaked API Token

Status: published. Published: 2026-11-03. Updated: 2026-11-03.

The WATI Chat and Notification WordPress plugin through 1.1.8 does not require a valid, non-empty secret on a public endpoint that returns its stored API token, which an unauthenticated attacker can then present to a second public endpoint to obtain the order-received URL of any WooCommerce order and read the customer's name, address, phone number and email address. The endpoints are reachable in the WATI Chat and Notification WordPress plugin through 1.1.8's default state and are closed only once a WATI account is connected.
