Summary
The LiteSpeed Cache plugin for WordPress, up to and including 7.9.1, caches WooCommerce Store API cart and checkout responses as public objects without varying them on the Cart-Token or session. An unauthenticated remote attacker can read another shopper's billing and shipping details, cart contents and totals, and the live Cart-Token session token, which enables session hijack. The flaw is classified as CWE-200.

Description from the CNA
The LiteSpeed Cache plugin for WordPress is vulnerable to unauthenticated disclosure of sensitive WooCommerce customer data in all versions up to, and including, 7.9.1 With Cache REST enabled (the shipped default cache-rest=1), LiteSpeed stores WooCommerce Store API GET responses (/wc/store/v1/cart and /wc/store/v1/checkout) as PUBLIC cache objects and does not vary the cache on the Cart-Token or WooCommerce session. A shopper's personalized cart/checkout response is therefore served to any later, cookie-less and token-less client as an LSCache HIT. This makes it possible for unauthenticated attackers to read another shopper's billing and shipping details (name, company, street address, email, phone), cart contents and totals, and the shopper's live Cart-Token session JWT and nonce (enabling cart/checkout-session hijack), plus order_key on the checkout endpoint.
