At a glance

CVE-2023-6781 is a medium-severity Improper Input Validation vulnerability in the Orbit Fox WordPress plugin, affecting versions <= 2.10.26. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 2.10.27; sites on affected versions should update now. Disclosed January 2024, reported by Nex Team.

Vulnerability Overview

The Orbit Fox by ThemeIsle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's custom fields in all versions up to, and including, 2.10.26 due to insufficient input sanitization and output escaping on user supplied values. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-20: Improper Input Validation

Reaching this weakness in Orbit Fox <= 2.10.26 takes an account at Contributor level or above. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Orbit Fox the fix is 2.10.27: builds <= 2.10.26 are affected, anything from 2.10.27 onward is not.

Remediation

Update to version 2.10.27, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Orbit Fox 2.10.27 closes this, and updating the plugin is the step that ends it.
