Unauthenticated wishlist renaming via missing ownership check

Published Apr 10, 2026 · Updated Apr 10, 2026

Missing authorization in YITH WooCommerce Wishlist before 4.13.0 allows remote attackers to rename any user's wishlist through AJAX. The save_title() handler accepts a caller-supplied wishlist ID and title after validating only a nonce exposed on the public wishlist page, without checking ownership. No account or user interaction is required; impact is limited to unauthorized modification of stored wishlist titles.
