What the vulnerability does
The BackWPup plugin for WordPress is vulnerable to Plaintext Storage of Backup Destination Password in all versions up to, and including, 4.0.2. This is due to to the plugin improperly storing backup destination passwords in plaintext. This makes it possible for authenticated attackers, with administrator-level access, to retrieve the password from the password input field in the UI or from the options table where the password is stored.

BackWPup versions up to 4.0.2 contain a flaw that allows high-privilege users to access limited sensitive information. The vulnerability requires administrator-level access and high attack complexity to exploit. The exposure is minimal—only low-level confidentiality impact—making this a low-severity issue for most sites.
What an attacker can do
Read limited sensitive information if they have administrator access.
