Summary
OpenRemote before 1.32.2 contains a stored cross-site scripting vulnerability that allows authenticated users with write:admin permissions to upload HTML or SVG files containing JavaScript via the Manager configuration file upload endpoint. Attackers can lure victims to the unauthenticated image retrieval endpoint, which serves files as text/html or image/svg+xml, executing scripts within the application's origin.
