This vulnerability in WP Rentals (versions <= 3.16.1) involves improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). An attacker with low privileges can inject malicious scripts that execute in the context of other users, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, required privileges low, user interaction required, and scope changed, with low impact on confidentiality and integrity and low impact on availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, session hijacking, or other client-side impacts. The impact is rated medium based on the CVSS score of 6.5. There are no reports of active exploitation in the wild.
