Wimi Teamwork

Wimi Teamwork On-Premises versions prior to 8.2.0 contain an insecure direct object reference vulnerability in the preview.php endpoint where the item_id parameter lacks proper authorization checks. Attackers can enumerate sequential item_id values to access and retrieve image previews from other users' private or group conversations, resulting in unauthorized disclosure of sensitive information.

Wimi Teamwork versions prior to 7.38.17 contains a cross-site request forgery (CSRF) vulnerability in its API. The API accepts any authenticated request that contains a JSON field named 'csrf_token' without validating the field’s value; only the presence of the field is checked. An attacker can craft a cross-site request that causes a logged-in victim’s browser to submit a JSON POST containing an arbitrary or empty 'csrf_token', and the API will execute the request with the victim’s privileges. Successful exploitation can allow an attacker to perform privileged actions as the victim potentially resulting in account takeover, privilege escalation, or service disruption.
