CVE-2026-4432: CWE-862 Missing Authorization in YITH WooCommerce Wishlist
CVE-2026-4432 is a missing authorization vulnerability in the YITH WooCommerce Wishlist WordPress plugin before version 4. 13. 0. The plugin's save_title() AJAX handler fails to properly verify wishlist ownership before allowing renaming operations. It only checks for a valid nonce, which is publicly exposed on the /wishlist/ page, enabling unauthenticated attackers to rename any user's wishlist on the site.
AI Analysis
Technical Summary
The YITH WooCommerce Wishlist plugin versions prior to 4.13.0 contain an authorization bypass vulnerability (CWE-862) in the save_title() AJAX handler. This handler does not validate that the requester owns the wishlist being renamed, relying solely on a nonce that is publicly accessible in the page source. As a result, unauthenticated attackers can rename any wishlist belonging to any user by exploiting this insufficient authorization check.
Potential Impact
An attacker without authentication can rename any user's wishlist on the affected site. This could lead to user confusion, potential disruption of user experience, and may facilitate further social engineering or targeted attacks by manipulating wishlist data. There is no indication of data disclosure or privilege escalation beyond wishlist renaming.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting access to the wishlist renaming functionality or disabling the affected AJAX handler if feasible. Monitor vendor channels for updates and apply patches promptly once released.
