CVE-2026-15094 is a reflected cross-site scripting vulnerability in the WP Hotel Booking WordPress plugin by thimpress. The vulnerability exists due to improper neutralization of input during web page generation, specifically in the 'check_in_date' parameter. This allows unauthenticated attackers to inject malicious scripts that execute in the context of a victim's browser when they click a crafted link. The vulnerability affects all versions up to and including 2.3.2. No official patch or remediation level has been confirmed at this time.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in information disclosure or session hijacking. The vulnerability requires user interaction (clicking a malicious link) and does not require authentication. There is no indication of impact on system availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid clicking on suspicious links involving the 'check_in_date' parameter in WP Hotel Booking. Monitor vendor channels for updates and apply patches promptly once released.
