#4422 closed defect (bug) (fixed)

Anyone can delete attachments

Description

An unregistered user can delete attachments through xmlrpc request:

<methodCall>
  <methodName>wp.uploadFile</methodName>
  <params>
    <param><value>1</value></param>
    <param><value>1</value></param>
    <param><value>1</value></param>
	<struct>
		<member><name>name</name><value>attachement_name</value></member>
		<member><name>overwrite</name><value>1</value></member>
	</struct>
  </params>
</methodCall>

I'll submit a partial fix -- I think that an user should only delete their own uploaded files.

Looks good to me, but I'm not an XML-RPC guru.

My diff pushes the overwrite feature even further down, to just before the upload gets saved.
