## What is CVE-2020-15085?

CVE-2020-15085 is a medium-severity vulnerability in mirumee saleor-storefront, published on 30 Jun 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

In Saleor Storefront before version 2.10.3, request data used to authenticate customers was inadvertently cached in the browser's local storage mechanism, including credentials. A malicious user with direct access to the browser could extract the email and password. In versions prior to 2.10.0 persisted the cache even after the user logged out. This is fixed in version 2.10.3. A workaround is to manually clear application data (browser's local storage) after logging into Saleor Storefront.
