 "title": "LifterLMS <= 10.3.0 - Authentication Bypass via REST API Key Route Restriction",
 "description": "The LifterLMS plugin for WordPress is vulnerable to an authentication restriction bypass in all versions up to, and including, 10.3.0. The REST API key authentication decided whether a request targeted a LifterLMS route by reading the request path. WordPress, however, serves the route given in a 'rest_route' request argument, which takes precedence over the path. This makes it possible for holders of LifterLMS API key credentials to authenticate requests to non-LifterLMS WordPress REST API routes as the user the key belongs to, beyond the intended scope of the key.",
