WordPress Duplicate Page and Post plugin <= 1.0 - Cross Site Scripting (XSS) Vulnerability

Published Mar 28, 2025 CVSS 3.1 · 5.9 Medium EPSS < 1% KEV · Not listed

Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Falcon Solutions Duplicate Page and Post duplicate-post-and-page allows Stored XSS.This issue affects Duplicate Page and Post: from n/a through <= 1.0.

Analysis

Technical impact

An attacker who can provide input to the Duplicate Page and Post plugin can store malicious scripts that will be rendered when the affected page or post is displayed. This stored cross‑site scripting flaw allows the attacker to execute arbitrary scripts in users’ browsers, enabling cookie theft, session hijacking, or defacement of the site content.

Affected Systems

The vulnerability affects all installations of Falcon Solutions Duplicate Page and Post plugin version 1.0 or earlier. The plugin’s development version is not known to be affected, but explicit support is limited to the stated vintage range.

Risk and Exploitability

The CVSS score of 5.9 indicates a moderate severity vulnerability. With an EPSS score below 1% and no listing in the CISA KEV catalog, the likelihood of exploitation at time of analysis is low. The likely attack vector is through the plugin’s administrative interface or data entry points that store user‑supplied content, which then propagates to front‑end pages accessible to visitors.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update the Duplicate Page and Post plugin to the latest available version, which is expected to contain the necessary input sanitization fix.
If no newer version exists, remove the plugin entirely and replace it with a more secure alternative that properly escapes output.
Ensure that any user‑generated content handled by the plugin is sanitized using WordPress’s built‑in escaping functions (e.g., esc_html, esc_attr) before storage, and restrict configuration access to trusted administrators.
