What the vulnerability does

01Description

The Moosend Landing Pages plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the moosend_landings_auth_get function in all versions up to, and including, 1.1.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the 'moosend_landing_api_key' option value.

Explanation of Vulnerability in Simple Terms

02Summary
