Full Disclosure of Authenticated Arbitrary File Deletion Vulnerability in WordPress Plugin with 300,000+ Installs

Yesterday we full disclosed an authenticated arbitrary file upload vulnerability in the WordPress plugin Meta Box, which has 300,000+, that we had spotted as it was introduced in to the plugin. Subsequent to that the plugin was closed on the Plugin Directory and that got flagged as part of our monitoring for the closure of any of the 1,000 most popular WordPress plugins (it has been a busy week for that, as six of them have been removed). When those plugins get closed we do a few quick security checks over the plugins to see if there might be any obvious security issue in the plugins, which we should be warning our customers about, even if that didn’t lead to the closure. In this case we knew why the plugin was closed, but we did those checks anyway, which led to us finding the plugin also contains an authenticated arbitrary file deletion vulnerability. That vulnerability looks like it was connected to the change that also introduced the authenticated arbitrary file upload vulnerability.
