CVE-2026-120555: Jupiter X Core directory traversal in file parameter

CVE-2026-120555 · Severity: medium · CVSS 5.3 · Published 2026-11-07

The Jupiter X Core plugin for WordPress, used to build and manage website content, contains a directory traversal vulnerability that allows unauthenticated attackers to read sensitive files from the uploads directory. While protections prevent access to critical files outside the uploads folder like wp-config.php, an attacker could still extract private user data, unpublished content, or other confidential information stored there.

Vendors: Wordpress.

Technical details

The vulnerability is a directory traversal flaw in the 'file' parameter that bypasses inadequate path validation. Although the plugin implements path confinement via strpos and realpath checks that restrict access to wp-content/uploads/, an attacker can still traverse within that directory to access unintended files without authentication. The attack vector is network-based with no authentication or user interaction required.
