Third one:
https://security.dxw.com/advisories/moving-any-file-php-user-has-access-to-in-bp-group-documents-1-2-1/
> Details
> ================
> Software: BP Group Documents
> Version: 1.2.1
> Homepage: http://wordpress.org/plugins/bp-group-documents/
> CVSS: 9 (High; AV:N/AC:L/Au:N/C:P/I:P/A:C)
>
>
> Description
> ================
> Moving any file PHP user has access to in BP Group Documents 1.2.1
>
> Vulnerability
> ================
> An admin user (or anybody, since there is a CSRF vulnerability in this
> form) can move any file the PHP user has access to to a location
> inside the uploads directory. From the uploads directory, they are
> likely to be able to read the file.
>
> Proof of concept
> ================
> As a logged in admin, visit a page containing this form and submit it
> (or add auto-submission, and cause a logged in admin to visit it):
> <form method="POST"
> action="http://localhost/wp-admin/options-general.php?page=bp-group-documents-settings">
> <input name="group" value="1">
> <input name="file" value="../../../../wp-config.php">
> <input type="submit">
> </form>
> This will cause the wp-config.php file to be moved to a location
> within wp-content/uploads. In my case it was
> wp-content/uploads/group-documents/1/1380203685-……..wp-config.php. In
> this example I broke a WordPress installation, leaving the site wide
> open to another person to come in and do the “famous five minute
> install”. There may also be handy config files laying around that you
> could read by moving them to the web root.
