The WP Travel Engine WordPress plugin before 6.8.5 does not perform authorization or ownership checks when loading a caller-supplied booking identifier in one of its unauthenticated cart actions, allowing unauthenticated attackers to disclose any customer's booking order details and their stored billing information, and to overwrite that customer's booking record with their own data.

The WP Travel Engine WordPress plugin before 6.8.1 does not properly validate the source of a user-supplied profile image path before moving the file, allowing authenticated users with subscriber-level access and above to relocate arbitrary files within the WordPress uploads directory into their own profile-image path. This removes the targeted media from its original location and can break content across the site.

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in WP Travel Engine allows Stored XSS.This issue affects WP Travel Engine: from n/a through 5.9.1.
