Edito CMS is vulnerable to Stored Cross-Site Scripting (XSS). Due to improper input validation, an authenticated attacker can inject malicious scripts into givenName and surname parameters via the /api/auth/profile endpoint. When an administrator visits the admin changelog logs, the injected script is automatically executed, in his browser.

This issue was fixed in version 5.10.2607.  Hotfixes for older versions (5.8) have also been released.
