AI Threat Summary

CVE-2026-111213 is a moderate vulnerability with a CVSS score of 4.3 affecting the target software. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

The Travelly – Tour & Travel Booking Manager for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.6 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 duplicate arbitrary posts — including private, draft, and pending posts authored by Administrators and Editors — into drafts they own, thereby exposing the original post's content, excerpt, title, taxonomies, and metadata. A Contributor can harvest a valid nonce from the Duplicate row-action on their own posts list and reuse it against any victim post ID, since the nonce action is the static string 'TTBM_Admin.php' and is not bound to any specific post.
