CVE-2026-109166
Description
A flaw was found in lamp-cloud. This vulnerability allows an authenticated remote attacker to cause an information disclosure by accessing files belonging to other users. The application fails to verify file ownership when retrieving file storage locations, enabling an attacker to supply arbitrary file identifiers and obtain direct access URLs for private attachments.
Statement
This vulnerability is assessed as having Moderate severity because exploitation requires an authenticated account and is limited to unauthorized disclosure of stored files, with no impact on data integrity or system availability. lamp-cloud is not packaged or supported within any Red Hat products, and standard Red Hat platform deployments are therefore unaffected.
