Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2025-65442

Medium
6.1/10

Summary

DOM-based Cross-Site Scripting (XSS) vulnerability in 201206030 novel V3.5.0 allows remote attackers to execute arbitrary JavaScript code or disclose sensitive information (e.g., user session cookies) via a crafted "wvstest" parameter in the URL or malicious script injection into window.localStorage. The vulnerability arises from insufficient validation and encoding of user-controllable data in the book comment module: unfiltered user input is stored in the backend database (book_comment table, commentContent field) and returned via API, then rendered directly into the page DOM via Vue 3's v-html directive without sanitization. Even if modern browsers' built-in XSS filters block pop-up alerts, attackers can use concealed payloads to bypass interception and achieve actual harm.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
