CVE-2026-1771Network attack vector

Administrator file upload via skipped type validation

Published Jul 21, 2026 · Updated Jul 21, 2026

Arbitrary file upload in RomanCode MapSVG 8.14.0 and earlier allows remote authenticated users to write files through the SVG endpoint. The SVGFile constructor uses an incorrect conditional check that skips file-type validation before accepting an uploaded file. Administrator-level access is required, and executable uploaded content enables server-side code execution when the server exposes it for execution.
