A critical vulnerability has been identified in the Post SMTP plugin for WordPress, affecting over 200,000 websites. This flaw allows attackers to gain control of the administrator account, posing significant risks to site security and data integrity. The Post SMTP plugin is widely used for managing email delivery in WordPress, making this vulnerability particularly concerning.

The vulnerability stems from a defective version of the plugin, which can be exploited to take over admin accounts.
