NodeBB versions prior to 4.15.0 are vulnerable to a stored cross-site scripting (XSS) flaw in the renderEmoji function, which improperly escapes certain attributes. This allows attackers to inject malicious HTML and JavaScript into posts, potentially executing code in the browsers of all users who view the content. Organizations using affected versions should prioritize patching to mitigate the risk of client-side attacks.
