A server-side request forgery (SSRF) vulnerability has been identified in Bytedesk versions through 1.3.9. The issue resides in the OpenRouter integration, specifically within the 'getModels' function of the 'SpringAIOpenrouterRestService' class. The vulnerability allows remote attackers to manipulate the 'apiUrl' parameter, leading to unauthorized outbound HTTP requests to arbitrary hosts. This could be exploited to access internal services, cloud metadata, or sensitive information such as credentials.
Users are advised to upgrade to Bytedesk version 1.4.5.4, which addresses this vulnerability. The update is available as a Docker image or as a downloadable zip file.
