This vulnerability (CVE-2025-30931) involves improper neutralization of input during web page generation in the «Подсказки» от DaData.ru product, leading to a stored Cross-site Scripting (XSS) issue. It affects versions up to 1.0.6 and allows an attacker with high privileges and user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 base score is 5.9, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS vector indicates that the attacker requires high privileges and user interaction, which reduces the likelihood and impact severity. No known exploits have been reported in the wild.
