Description
WordPress Plugin Recent Backups 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 Recent Backups version 0.7 is vulnerable; prior versions may also be affected.
Remediation
Edit the source code to ensure that input is properly verified or disable the plugin until a fix is available
