This vulnerability in Elfsight Yottie Lite (<= 1.3.3) involves improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). An attacker with high privileges and requiring user interaction could inject malicious scripts that execute in a context with potentially elevated privileges, impacting confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, and user interaction needed, with scope changed and partial impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users interacting with the affected application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The impact is rated medium due to the requirement of high privileges and user interaction, and the partial compromise of confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply strict input validation and output encoding as a temporary mitigation. Monitor vendor channels for updates regarding patches or official fixes.
