Stored XSS in Lpagery WordPress Plugin

Publication date: 2026-07-23

Last updated on: 2026-07-23

Assigner: Wordfence

Description
The Lpagery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in versions up to, and including, 2.5.7. This is due to insufficient input sanitization and output escaping in the lpagery_add_filter_text_template_post() function, which is hooked to admin_footer and echoes the raw post_title of the post referenced by the ?lpagery_template query parameter directly inside a JavaScript single-quoted string literal, without esc_js(), esc_html(), or any other encoding. 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 higher-privileged user (such as an administrator) accesses an admin page with the ?lpagery_template=<post_id> parameter pointing at the attacker's post.

Executive Summary

The Lpagery WordPress plugin up to version 2.5.7 has a stored cross-site scripting (XSS) vulnerability. It occurs because the plugin does not properly sanitize post titles before outputting them in JavaScript code. Attackers with Contributor-level access or higher can inject malicious scripts via post titles, which execute when an admin views a page with a specific parameter.

Detection Guidance

Check for WordPress sites using the Lpagery plugin version 2.5.7 or lower. Inspect post titles for unusual JavaScript content, especially in URLs with the ?lpagery_template parameter. Use WordPress admin access logs to identify Contributor-level users creating posts with suspicious titles.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into WordPress admin pages. If exploited, it could lead to unauthorized actions, data theft, or session hijacking for users with admin privileges. The impact depends on the attacker's goals and the site's configuration.

Compliance Impact

This vulnerability could compromise data integrity and confidentiality, potentially violating GDPR (data protection) and HIPAA (health data privacy) requirements. Unauthorized script execution may lead to data breaches, requiring incident reporting and possible fines under these regulations.

Mitigation Strategies

Update the Lpagery plugin to the latest version. Remove or disable the plugin if no update is available. Review and sanitize post titles for any injected scripts. Restrict Contributor-level user permissions to minimize attack surface.
