## FAQ

### What does this mean?

The bug is an XML external entity (XXE) flaw, which lets crafted XML make the software read data it should not reach. Per the title, this can expose the crypt key and other secrets, which can lead to full admin access. The listed impact also cites arbitrary code execution via nested deserialization, with potential data breaches and system compromise.

### Am I affected, and how do I check?

The conditions say Adobe Commerce and Magento versions 2.4.6 and earlier are affected. The product data lists Adobe Commerce up to 2.4.4-p8, magento/community-edition from 0 up to but not including 2.4.4-p9, from 2.4.5-p1 to before 2.4.5-p8, and from 2.4.6-p1 to before 2.4.6-p6. To check your installation, look at your installed Magento or Adobe Commerce version, for example with bin/magento --version.
