CVE-2026-48118: NukeViet: Unauthenticated Reflected XSS in Comment Module

July 13, 2026

Reflected XSS in the Comment module via the status_comment URL parameter. The parameter accepts attacker-controlled base64-encoded HTML/JavaScript that is decoded server-side and rendered unescaped into the page. Compounded by a second flaw: the checkss anti-forgery token was derived from a site-wide static value (NV_CACHE_PREFIX) instead of a per-session value, making the token reusable across all users and allowing the attack to be delivered via a simple crafted URL.
