CVE-2024-1639 | License Manager for WooCommerce <= 3.0.6 - Improper Authorization to Authenticated(Contributor+) Sensitive Information Exposure

The License Manager for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the showLicenseKey() and showAllLicenseKeys() functions in all versions up to, and including, 3.0.6. This makes it possible for authenticated attackers, with admin dashboard access (contributors by default due to WooCommerce) to view arbitrary decrypted license keys. The functions contain a referrer nonce check. However, these can be retrieved via the dashboard through the "license" JS variable. Please note that the version in trunk is patched, however, the 3.0.7 tagged version is not.
