WordPress Plugin Lazy SEO is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly 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 Lazy SEO version 1.3.2 is vulnerable; prior versions are also affected.
Update to plugin version 1.4.0 or latest
