CVE-2026-2437 is a stored cross-site scripting vulnerability in the WP Travel Engine – Tour Booking Plugin for WordPress, specifically in the 'wte_trip_tax' shortcode. The vulnerability is due to improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject malicious scripts via insufficiently sanitized shortcode attributes. These scripts execute in the context of users who access the injected pages, 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, reflecting a medium severity with network attack vector, low complexity, and privileges required at the contributor level.

An attacker with contributor-level access or higher can inject malicious scripts that execute in the browsers of users who view the affected pages. This can lead to information disclosure or session hijacking limited to the privileges of the injected script. The vulnerability does not allow denial of service or privilege escalation beyond the contributor level. No known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'wte_trip_tax' shortcode. Monitor for updates from the WP Travel Engine vendor and apply patches promptly once available.
