What is CVE-2026-35023?

The Wimi Teamwork On-Premises product versions before 8.2.0 suffer from a vulnerability in the preview.php endpoint. The issue arises from inadequate authorization checks on the item_id parameter, allowing attackers to sequentially enumerate item_id values. This weak control enables unauthorized users to access and retrieve image previews from private or group conversations of other users, leading to a breach of sensitive information.

Affected Version(s)
