This vulnerability in LearnPress – Course Review allows stored XSS due to improper input sanitization when generating web pages. Attackers with low privileges can inject malicious scripts that persist and execute when other users view the affected content. The issue affects all versions up to 4.1.9. The CVSS vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability at a low level. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation can lead to execution of arbitrary scripts in the context of users viewing the compromised course reviews, potentially leading to session hijacking, data theft, or other client-side impacts.
