Stored XSS in Powerkit WordPress Plugin via Lazy Load Module

Publication date: 2026-09-07

Last updated on: 2026-09-07

Assigner: Wordfence

Description
The Powerkit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Lazy Load module's image processing in all versions up to, and including, 3.0.4. This is due to the 'content_process_images' function using a flawed regex-based HTML attribute parser. 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.

Executive Summary

The Powerkit plugin for WordPress has a stored Cross-Site Scripting (XSS) vulnerability in its Lazy Load module. This flaw exists in versions up to 3.0.4 due to a flawed regex-based HTML attribute parser in the 'content_process_images' function. Authenticated attackers with Contributor-level access or higher can inject malicious scripts into pages.

Detection Guidance

Check for the Powerkit plugin version 3.0.4 or lower in your WordPress installation. Look for unauthorized script injections in pages using the Lazy Load module. Inspect HTML output for suspicious script tags or attributes in image processing functions.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into WordPress pages. When users access these pages, the scripts execute, potentially stealing user data, session cookies, or performing actions on behalf of the user. It requires Contributor-level access but can affect all visitors to the site.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR and HIPAA requirements for protecting user data. If exploited, it may result in unauthorized access to personal or sensitive information, leading to legal penalties and loss of compliance certifications.

Mitigation Strategies
  • Update the Powerkit plugin to the latest version immediately to patch the vulnerability.
  • Review user roles with Contributor-level access or higher for unauthorized changes.
  • Scan your WordPress site for existing malicious scripts or injected content.
