NukeViet CMS versions prior to 4.6.00 contain a stored cross-site scripting (XSS) vulnerability. A low-privileged authenticated user can inject JavaScript payloads into their profile's display name fields, which execute in the browsers of visitors who click the Reply link on that user's comment. The vulnerability arises from improper escaping of user input placed inside a JavaScript string literal within an HTML attribute, allowing execution of arbitrary scripts. This can lead to privilege escalation, credential phishing, and data exfiltration. The vulnerability affects the comment template's inline onclick handler and is exploitable under default configurations without CAPTCHA or moderation. No official patch is currently documented, but remediation involves removing the vulnerable inline handler or properly escaping the input with JSON encoding.
