WooCommerce permits unauthenticated HTTP resource-exhaustion denial of service
WooCommerce before 11.1.0 allocates resources without sufficient limits or throttling when handling HTTP requests. An unauthenticated attacker can abuse that processing to exhaust resources and disrupt the store, without another user interacting with the request. The CNA rates high availability impact and no confidentiality or integrity impact. Version 11.1.0 is identified as unaffected.
