CVE-2026-121794
Travelly <= 2.3.11 - Missing Authorization to Authenticated (Contributor+) Payment Gateway Credential Disclosure via edit_form_top Handler on Tour/Hotel Edit Screen
Description
The Travelly – Tour & Travel Booking Manager for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.11 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to view stored WooCommerce payment gateway credentials — including PayPal API username, password, and signature, as well as Stripe test and live secret keys — injected verbatim into the HTML response of the tour edit screen. The credentials are present in the raw HTTP response regardless of the modal's CSS visibility state, making them trivially accessible by viewing page source.
