Edito CMS is vulnerable to improper cryptographic signature verification in the JWT refresh logic. An authenticated low-privilege user can submit self-crafted JWT containing an existing user identifier and, due to the lack of signature validation, obtain a valid, fully-signed session token for any account in the system. This allows the attacker to impersonate any user, including administrators. This issue was fixed in version 5.10.2607. Hotfixes for older versions (5.8) have also been released.
