Web-shell upload via unrestricted file handling

Published Oct 20, 2024 · Updated Apr 28, 2026

Unrestricted file upload in brx8r Nice Backgrounds 1.0 and earlier allows attackers to place a web shell on the server. Published sources do not identify the affected upload handler or the exact validation failure that permits dangerous file types. The CNA record treats access as unauthenticated, while WPScan reports Subscriber-level access; a successful upload permits code execution under the web server account.
