Vulnerabilidades do Niklaslindemann Bulk Page Generator – LPagery

The Bulk Page Generator – LPagery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.1.0 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to create, modify, and delete LPagery-managed WordPress pages and bulk page-generation processes that are otherwise restricted to administrators. On default fresh installations where Freemius has not been opted into, the AES-256-CBC key used to validate Bearer tokens collapses to the publicly known SHA-256 hash of an empty string, making the token entirely forgeable by any authenticated user.

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.
