## Summary

OpenRemote versions before 1.32.2 have a stored cross-site scripting flaw in the Manager configuration file upload feature. An attacker who can log in with high-level admin rights over the network can upload an HTML or SVG file with embedded JavaScript, then lure a victim to open it so the script runs in the application's origin.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- openremote core: fixed in 1.32.2

## Description

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.
