Bulk Page Generator <= 2.5.7 — Authenticated (Contributor+) Stored Cross-Site Scripting via Post Title

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Bulk Page Generator – LPagery.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 2.5.8, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Bulk Page Generator – LPagery to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wordfence PRISM.

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.
