Description

WordPress Plugin Duplicator-WordPress Migration 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 Duplicator-WordPress Migration version 1.3.26 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 1.3.28 or latest
