## Description

The Password Protect Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's [ppwp] shortcode in all versions up to, and including, 1.9.26 due to insufficient input sanitization and output escaping when building the password form template, where user-supplied shortcode attribute values could contain placeholder tokens that were later expanded in an already-escaped context. 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.
