Description

Nexent through 2.7.0 contains a missing authorization vulnerability in check_file_access that allows authenticated users to read other tenants' knowledge-base files by skipping tenant comparison for knowledge_base/ reads. Attackers in multi-tenant deployments can list objects via GET /file/storage for presigned URLs or use GET /file/download/{object_name} to download other tenants' source documents.
