CVE-2026-4432: Unknown Yith Woocommerce Wishlist

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

The YITH WooCommerce Wishlist WordPress plugin before 4.13.0 does not properly validate wishlist ownership in the save_title() AJAX handler before allowing wishlist renaming operations. The function only checks for a valid nonce, which is publicly exposed in the page source of the /wishlist/ page, making it possible for unauthenticated attackers to rename any wishlist belonging to any user on the site.
