The wpdevelop Booking Manager plugin suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows an attacker with low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users' browsers, potentially leading to partial confidentiality, integrity, and availability impacts. The vulnerability affects all versions up to 2.1.18. No vendor advisory or patch information is provided, and the plugin is not a cloud service.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to partial disclosure of information, modification of data, or disruption of service. The CVSS vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change, with low impacts on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the affected plugin and monitor for suspicious activity. Avoid exposing the Booking Manager plugin to untrusted users where possible.
