Omnispace Agora Project 26.10.0 IDOR via reloadMailTypeId Parameter

Published Nov 13, 2026 CVSS 4.0 · 7.1 High EPSS n/a KEV · Not listed

Description

Omnispace Agora Project through 26.10.0 contains an insecure direct object reference vulnerability that allows authenticated attackers to access another user's private mail by supplying a crafted reloadMailTypeId parameter to Ctrl::getCurObj() without a readRight() ownership check in CtrlMail.php. Attackers can manipulate the mail identifier value, such as reloadMailTypeId=mail-1, to retrieve the title and body of private messages belonging to other users, resulting in unauthorized disclosure of sensitive communications.
