This vulnerability in Webba Booking (versions <= 6.0.5) involves improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker could inject malicious scripts that are stored by the application and later executed in the context of other users' browsers. The CVSS v3.1 base score is 5.9, with network attack vector, low attack complexity, high privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability rated as low to low and low respectively.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to execute arbitrary scripts in the context of other users, potentially leading to partial confidentiality, integrity, and availability impacts within the affected application environment. No known active exploitation has been reported.
