Technical details

The plugin stores WooCommerce Store API responses (/wc/store/v1/cart and /wc/store/v1/checkout) as PUBLIC cache objects without varying the cache on Cart-Token or WooCommerce session identifiers when Cache REST is enabled (default). This allows any unauthenticated client to retrieve a cached response belonging to a previous shopper, exposing billing/shipping details, cart contents, session JWTs, nonces, and order keys. The vulnerability requires network access and affects all versions up to 7.9.1.
