Description
WordPress Plugin Gmedia Photo Gallery is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because the application fails to adequately sanitize user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Gmedia Photo Gallery version 1.2.1 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.2.2 or latest
