Wimi Teamwork
Monthly
Wimi Teamwork On-Premises versions before 8.2.0 allow authenticated attackers to enumerate sequential item_id values in the preview.php endpoint to bypass authorization checks and access image previews from other users' private or group conversations, resulting in unauthorized information disclosure. The vulnerability requires valid user credentials (CVSS PR:L) but enables horizontal privilege escalation to retrieve sensitive conversation data. No public exploit code has been identified, though the IDOR vulnerability pattern is straightforward to exploit.
