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.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
