A stored XSS vulnerability in EspoCRM 5.6.8's email signature field (exploited via polyglot payload bypassing sanitization) allows attackers to steal authentication cookies when victims reply to emails, enabling complete account takeover of any user including admins. The vulnerability stems from unprotected HttpOnly cookies containing Base64-encoded credentials that can be extracted via malicious JavaScript.
