Detailsinfo

A vulnerability was found in givanz Vvveb up to 1.0.8.4. It has been declared as critical. Affected by this vulnerability is the function saveGlobalElements of the file admin/controller/editor/global-trait.php of the component Editor. The manipulation of the argument data-v-save-global with an unknown input leads to a permission vulnerability. The CWE definition for the vulnerability is CWE-275. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-54612 since 06/15/2026. The exploitation appears to be easy. The attack can be launched remotely.
