CVE-2026-57799Network attack vector

Authenticated code execution via local PHP file inclusion

Published Jul 13, 2026 · Updated Jul 13, 2026

Local file inclusion in Uxper Nuss 1.3.6 and earlier allows remote authenticated users to execute PHP code through the WordPress site. Published materials identify attacker-controlled filename use by a PHP include or require operation but do not disclose the affected file, function, or request parameter. Contributor-level access is required, and code execution depends on an includable server file containing PHP code; otherwise, local file contents can be exposed.
