At a glance

CVE-2026-10511 is a medium-severity Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in the Jupiter X Core WordPress plugin, affecting versions <= 4.61.0. 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.

Vulnerability Overview

The Jupiter X Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'forget_password_link' parameter in all versions up to, and including, 4.61.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, 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-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

Remediation

Update to version 4.62.0, 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: Jupiter X Core 4.62.0 closes this, and updating the plugin is the step that ends it.
