Description
WordPress Plugin Zip Attachments is prone to a vulnerability that lets attackers download arbitrary files because the application fails to sufficiently verify user-supplied input. This may allow an attacker to gain access to sensitive information, which may aid in launching further attacks. WordPress Plugin Zip Attachments version 1.4 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.5 or latest
