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 Bliss Gallery version 2.3 is vulnerable; prior versions may also be affected.
