Stored XSS on first/last name during setup was found in Passbolt before v2.11.0. An administrator can craft a user with a malicious first name and last name, using a payload such as The user will then receive the invitation email and click on the setup link. The setup's start page served by the server will fire the XSS. An administrator could use this exploit to edit the setup start page for a given user, for example, trick the user into installing another extension. Even though the severity of this issue in itself is high, the likelihood is low because the exploit will be visible in clear by the user in the email notification, and also requires action from a malicious administrator.
