This vulnerability in If-So Dynamic Content Personalization (<= 1.9.4) is due to improper input sanitization during web page generation, resulting in Stored Cross-site Scripting (XSS). An attacker with low privileges can inject malicious scripts that execute when other users view the affected content. The CVSS 3.1 score is 6.5, reflecting network attack vector, low attack complexity, requiring privileges and user interaction, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, modification of content, or disruption of service. The impact is limited by the requirement for low privileges and user interaction, and the overall severity is medium.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict privileges to trusted users and consider disabling or limiting use of the affected plugin to reduce exposure.
