FKIE_CVE-2026-54612

Vulnerability from fkie_nvd - Published: 2026-09-17 22:17 - Updated: 2026-09-18 20:17
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. From 1.0.0 until 1.0.8.5, saveGlobalElements() in admin/controller/editor/global-trait.php concatenates the attacker-controlled file portion of data-v-save-global to the active theme directory before loadHTMLFile() and file_put_contents() operate on it. An authenticated user with the default Editor role and editor/* permission can submit crafted HTML to module=editor/editor&action=save and traverse to an existing writable PHP file outside the theme directory. If the target is web-accessible, editor-controlled PHP content executes in the web server context; a shipped public/vadmin/index.php entrypoint can be used as an execution trampoline rather than requiring a test-only file. This can permit persistent webshell placement and compromise application confidentiality, integrity, and availability. This issue is fixed in version 1.0.8.5.
