MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
The Child Height Predictor by Ostheimer plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to and including 1.3. Missing nonce verification in the options() function allows unauthenticated attackers to trick an administrator into clicking a link or visiting a malicious page, resulting in unauthorized changes to plugin settings (e.g., unit preferences) persisted in the database.
Risk Assessment
An attacker can change plugin settings without administrator consent, potentially causing incorrect behavior or displaying erroneous data.
Recommendation
Update the plugin to a version with proper nonce validation. If unavailable, consider temporarily disabling the plugin.
Original NVD description (English source)
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().
