Stored XSS in Content Mask WordPress Plugin

Publication date: 2026-09-09

Last updated on: 2026-09-09

Assigner: WPScan

Description
The Content Mask WordPress plugin before 1.8.5.6 does not properly sanitise and escape content submitted with a post before outputting it in the pages it generates, allowing users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks against any user viewing or previewing the affected page. The Content Mask WordPress plugin before 1.8.5.6's option to restrict its use by role does not prevent this.

Executive Summary

The Content Mask WordPress plugin before version 1.8.5.6 has a stored cross-site scripting (XSS) vulnerability. It fails to properly sanitize and escape user-submitted content in posts, allowing attackers with Contributor-level access or higher to inject malicious scripts. These scripts execute when other users view or preview the affected pages.

Detection Guidance

Check the installed version of the Content Mask WordPress plugin. If it is between 1.7.1 and 1.8.5.5, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin files for version details.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into web pages. If you view or preview an affected page, the injected script could steal your session cookies, redirect you to phishing sites, or perform actions on your behalf without your consent.

Compliance Impact

This vulnerability could lead to data breaches by allowing attackers to steal sensitive user data, which may violate GDPR's data protection requirements. For HIPAA, it could compromise protected health information if exploited on healthcare-related sites.

Mitigation Strategies

Update the Content Mask plugin to version 1.8.5.6 or later immediately. If updating is not possible, consider disabling the plugin until an update is applied to prevent exploitation.
