Summary

The SKU Error Fixer for WooCommerce WordPress plugin through 1.0 does not perform any capability or nonce checks on two of its AJAX actions, which are also available to unauthenticated users, allowing them to permanently delete product variations it classifies as obsolete, and to disclose those variations' details, with no recoverable copy left behind.
