NodeBB (before v4.14.0): stored/reflected XSS in topic-event rendering. User-controlled values (avatar picture, display name, icon color/text, userslug) were interpolated into HTML in buildAvatar/renderUser without escaping, allowing script injection. Fixed in 4.14.0 by escaping all values. One of eight high-severity flaws disclosed by Aikido Security; no CVE assigned.
