ragent 1.1.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject scripts by uploading SVG knowledge-base documents served inline as image/svg+xml. Attackers can upload a script-bearing SVG via /knowledge-base/{kb-id}/docs/upload so that victims opening /knowledge-base/docs/{docId}/file execute it in the application origin, enabling account takeover.
