helpstring vulnerabilities and threats

The Global Body Mass Index Calculator WordPress plugin up to version 1.2 is vulnerable to stored cross-site scripting (XSS) via its 'gbmicalc' shortcode. This vulnerability arises from improper sanitization and escaping of user-supplied shortcode attributes, which are directly extracted and echoed into HTML contexts without sufficient neutralization. Authenticated users with contributor-level access or higher can inject malicious scripts that execute when other users view the affected pages. The vulnerability has a CVSS 3.1 score of 6.4, indicating a medium severity level.

The Child Height Predictor by Ostheimer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.3. This is due to missing nonce verification in the options() function, which handles plugin settings updates. The form template does not include a wp_nonce_field() call, and the handler never calls check_admin_referer() or wp_verify_nonce(). This makes it possible for unauthenticated attackers to trick a site administrator into clicking a link or visiting a malicious page that submits a forged POST request, causing unauthorized changes to the plugin settings such as unit preferences to be persisted to the database via update_option().
