CVE-2026-109168
Description
A flaw was found in lamp-cloud. This flaw allows an authenticated remote attacker to cause information disclosure by submitting arbitrary business identifiers to the listFileByBizId endpoint due to an insecure direct object reference (IDOR, a failure to verify access permissions for requested data). Successful exploitation enables unauthorized users to view file metadata and retrieve attachments belonging to other business objects.
Statement
This vulnerability is rated with a Moderate severity impact because exploitation requires valid credentials and is restricted to unauthorized read access without allowing arbitrary data modification or service disruptions. Furthermore, lamp-cloud is not packaged, shipped, or supported in Red Hat products. As a result, standard Red Hat enterprise environments are not affected by this vulnerability.
