This vulnerability in devsoftbaltic SurveyJS (<= 1.12.20) involves improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker could inject malicious scripts that persist and execute in the context of users viewing the affected survey pages. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impact on confidentiality, integrity, and availability rated as low to low and low respectively.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to data disclosure, modification, or disruption of service. The impact is rated medium due to the stored nature of the XSS and the requirement for some privileges and user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying input validation and output encoding as a temporary mitigation to reduce the risk of stored XSS. Monitor vendor communications for updates on patches or official fixes.
