AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Unauthenticated network request with no interaction leaks high-value credentials, so PR:N/UI:N/C:H; base integrity is N since writes occur through a separate WooCommerce API auth step (downstream, out of base scope).

The MgoSync WordPress plugin before 2.1.7 does not have authorization controls on one of its REST API endpoints, allowing unauthenticated users to retrieve the stored WooCommerce API credentials, including a read/write consumer key and secret, from a configured site.
AnalysisAI
Unauthenticated, network-reachable attackers can read the WooCommerce API consumer key and secret stored by the MgoSync WordPress plugin in any version before 2.1.7, because one of its REST API endpoints performs no authorization check (CVSS 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Exploitation is trivial and publicly available exploit code exists, though the leak only yields credentials on sites that have completed the MgoSync WooCommerce credential setup; from there, read/write access to the connected store's REST API further depends on that API being reachable and the leaked key retaining its original scope. …

Recommended ActionAI
Within 24 hours, inventory all WordPress sites using the MgoSync plugin and upgrade every instance below 2.1.7 to vendor-released version 2.1.7; for any site where MgoSync WooCommerce credentials were configured, immediately rotate the WooCommerce API consumer key and secret because the exposed key is read/write, then review WooCommerce REST API access logs for unauthorized activity. …
