Technical details
The LearnPress plugin before version 4.3.7 suffers from a missing authorization vulnerability (CWE-862) within its REST API implementation. Specifically, the plugin does not verify the 'edit_users' capability when the 'edit' context is requested on the 'learnpress/v1/users' endpoint. An unauthenticated remote attacker can exploit this by sending a crafted GET request with the 'context=edit' parameter. Successful exploitation allows the attacker to retrieve sensitive metadata for all returned users, including their roles, full capabilities map, extra capabilities, locale, and registration dates. This bypasses the standard security controls typically enforced by WordPress core for user data.
