CVE-2026-35023
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.
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
Description
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.
