Post SMTP plugin flaw exposes 200K WordPress sites to hijacking attacks

The security issue affects all versions of Post SMTP up to 3.2.0 and is due to a broken access control mechanism in the plugin’s REST API endpoints, which only verified if a user was logged in, without checking their permission level. More than 200,000 WordPress websites are using a vulnerable version of the Post SMTP plugin that allows hackers to take control of the administrator account. A notable 24.2%, corresponding to 96,800 sites, still run Post SMTP versions from the 2.x branch, which is vulnerable to additional security flaws, leaving them open to attacks. Download statistics on WordPress.org show that less than half of the plugin's user base (48.5%) has updated to version 3.3. This means that more than 200,000 websites are vulnerable to CVE-2025-24000. On vulnerable sites, a subscriber could initiate a password reset for an Administrator account, intercept the reset email via the logs, and gain control of the account. Post SMTP is a popular email delivery plugin for WordPress that counts more than 400,000 active installations.

The solution was to incorporate additional privilege checks in the ‘get_logs_permission’ function that would validate a user’s permissions before giving access to sensitive API calls.
