CVE-2026-2437 is a stored cross-site scripting vulnerability in the WP Travel Engine – Tour Booking Plugin for WordPress. The issue is due to improper neutralization of input during web page generation, specifically in the 'wte_trip_tax' shortcode. Authenticated attackers with contributor or higher privileges can inject malicious scripts via insufficiently sanitized and escaped user input. These scripts execute whenever a user accesses the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 6.7.5. The CVSS 3.1 score is 6.4 (medium severity), with attack vector network, low attack complexity, privileges required at the contributor level, no user interaction needed, and impacts confidentiality and integrity with no impact on availability. No patch or official remediation level has been published by the vendor as of the data provided.

Successful exploitation allows authenticated users with contributor-level access or higher to inject and execute arbitrary JavaScript in the context of the affected site. This can lead to unauthorized actions such as session hijacking or data manipulation for users who view the injected content. The confidentiality and integrity of user data may be compromised. There is no impact on availability. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'wte_trip_tax' shortcode if feasible. Monitor vendor channels for updates regarding patches or official mitigations.
