AIOS WordPress Plugin Stored Plaintext Passwords Reportedly, the developer team behind the AIOS WordPress plugin has released a significant update addressing a severe security flaw. According to their advisory, the plugin vulnerability resulted in logging users’ passwords in plaintext in the WordPress database. The flaw severely risked the WordPress websites’ security if the admins reused the same passwords on other services’ accounts without two-factor authentication.

These include copywriting protection, iFrame prevention to limit content theft, comment spam filtering, and a web application firewall.
