CVE-2026-8883 (GCVE-0-2026-8883)

Vulnerability from cvelistv5 – Published: 2026-06-09 03:41 – Updated: 2026-06-09 14:12

Title
Global Body Mass Index Calculator <= 1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes
Summary
The Global Body Mass Index Calculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gbmicalc' shortcode in versions up to, and including, 1.2. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes in the GBMI_Calc_Widget::widget() function. Shortcode attributes are extracted directly into local variables via @extract($args) and then echoed unescaped into an HTML style attribute (height/width) and HTML body context (title), allowing attribute-breakout payloads. 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.

CVE-2026-6400 (GCVE-0-2026-6400)

Title
Child Height Predictor by Ostheimer <= 1.3 - Cross-Site Request Forgery to Settings Update via Plugin Settings Form
Summary
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().
