Technical details
Froala Editor 3.2.6 contains a persistent XSS vulnerability (CWE-79) in the hyperlink creation module. The vulnerability is triggered when a specially crafted base64-encoded string is processed during hyperlink creation. The attack requires user interaction (opening/editing a malicious hyperlink) but does not require authentication. Once injected, the XSS payload persists in the document, affecting all users who view or edit that content. The vulnerability has been fixed in later versions.
