Impact Through the store-api it is possible as a attacker to check if a specific e-mail address has an account in the shop. Using the store-api endpoint `/store-api/account/recovery-password` you get the response ``` {"errors":[{"status":"404","code":"CHECKOUT__CUSTOMER_NOT_FOUND","title":"Not Found","detail":"No matching customer for the email \[email protected]\u0022 was found.","meta":{"parameters":{"email":"[email protected]"}}}]} ``` which indicates clearly that there is no account for this customer. In contrast you get a success response if the account was found. Patches Update to Shopware 6.6.10.3 Workarounds For older versions of 6.5 or 6.4, corresponding security measures are also available via a plugin.
