Server-side request forgery via unchecked API URL
Published Mar 8, 2026 · Updated Mar 8, 2026
Server-side request forgery in Bytedesk 1.3.0 through 1.3.9 allows remote authenticated users to make server-originated HTTP requests. The getModels method appends /models to the unvalidated apiUrl parameter and passes the resulting attacker-controlled URL to RestTemplate.exchange. A low-privilege account is required; successful exploitation reaches attacker-selected HTTP endpoints from the server and can probe internal services.
