org.xwiki.platform:xwiki-platform-attachment-api vulnerable to Missing Authorization on Attachment Move
Impact
An attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document. This allows the attacker to access and possibly publish any attachment of which the name is known, regardless if the attacker has view or edit rights on the source document of this attachment. Further, the attachment is deleted from the source document. This vulnerability exists since the introduction of attachment move support in XWiki 14.0 RC1.
Patches
This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1.
Workarounds
There is no workaround apart from upgrading to a fixed version.
