Description
WordPress Plugin Slideshow Gallery LITE 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 Slideshow Gallery LITE version 1.4.6 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.4.7 or latest
