A flaw was found in ceph-dashboard. The JSON Web Token (JWT) used for user authentication is stored by the frontend application in the browser’s localStorage which is potentially vulnerable to attackers via XSS attacks. The highest threat from this vulnerability is to data confidentiality and integrity.
Mitigation
Do not store sensitive data in HTML5 localStorage, not even temporarily. Use cookies with appropriate security flags (secure, HttpOnly, SameSite).
