No sign of exploitation. No public exploitation artifact known so far.
A sensitive cookie in TopEase Platform lacks the HTTPOnly flag, allowing attackers to steal it through JavaScript and hijack user accounts. This vulnerability lets unauthenticated users gain authenticated access by injecting a stolen session cookie.
The session-independent static UID cookie is missing the HTTPOnly flag, enabling XSS attacks to exfiltrate the cookie via JavaScript. An unauthenticated attacker can steal and replay this cookie to escalate privileges to authenticated user status on affected TopEase Platform versions ≤7.1.27.
In the same product, most dangerous first.
