The Pochipp plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'keyword' parameter in versions up to, and including, 1.20.2. This is due to insufficient output escaping , which reads $_GET['keyword'], applies only sanitize_text_field() (which strips tags but leaves double quotes intact) and interpolates the value directly into the value attribute of the search input via a PHP heredoc, without esc_attr(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user with upload_files capability (Author or above) into performing an action such as clicking on a specially crafted link to /wp-admin/media-upload.
