Auth bypass in Artbees Jupiter X Core
CVE-2026-120555
The Jupiter X Core plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 4.62.0 via the 'file' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The path confinement check introduced in the CVE-2023-3813 fix (strpos + realpath) is present and working, so reads are confined to wp-content/uploads/ and cannot reach wp-config.php or other files outside that directory.
