I'm stuck with an old version that I haven't been able to update yet, and it recently started uploading images and documents with full write permissions. The TinyMCE support team tells me that's not possible, but that sure is what it looks like to me.
By my recollection TinyMCE on it's own doesn't do uploading - it's pure client-side code so is incapable of doing so. Are you talking about an official or 3rd party extension or plugin that has a server-side component?
I think it's the official file manager extension that's doing it - though with the old version that I have, the file manager came built in instead of as an optional (paid, now) extension.
