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.
