👉 Enables custom headers for WP email notifications 👉 Also provides a “set it and forget it” security fix for WP < 5.5 👉 Uses only 50KB of code, so super lightweight, fast, and effective Important As of WordPress 5.5, this plugin no longer is necessary to fix the host-header security issue reported in Ticket #25239 finally is fixed, and mentioned in this post WordPress 5.5 Beta 4. Thank You WordPress devs! Is this plugin still useful? Yes, it enables you to choose the “From”, “Name”, and “Return-Path” headers for all WP notification emails. And for versions of WordPress less than 5.5, this plugin continues to fix the host-header injection security issue. Features This simple plugin does three things: Sets custom From, Name, and Return-Path for WP notifications Fixes a security vulnerability in WordPress versions < 5.5 Fixes a bug where invalid email addresses may be generated (in WordPress versions < 5.5) Choose from the following options: Use WordPress defaults (insecure for WP < 5.5) Use “Email Address” from WP General Settings Use a custom name and address Plus there is an option to use the specified From address as the Return-Path header. Why? The security issue fixed by this plugin has been known about since way back in WordPress version 2.3. There has been some talk about fixing, but nothing has been implemented. While the issue does not affect all sites, it does affect a good percentage of them, including some of my own projects. So, not wanting to get hacked, I decided to write my own solution. Hopefully this issue gets fixed in a future version of WordPress, and this plugin will become unnecessary. As a bonus, setting an explicit From address resolves a long-standing bug whereby an invalid email address is generated under the following conditions: A “From” address is not set, And the $_SERVER['SERVER_NAME'] is empty So by explicitly setting a “From” address, we prevent this bug from happening. Security Issue What is the security issue addressed by this plugin? Follows is a quick summary. To learn more in-depth, check out the resources linked in the next section. WP uses $_SERVER['SERVER_NAME'] to set the “From” header in email notifications This includes sensitive email notifications like password resets and user registration In some cases, an attacker could modify the “From” header and intercept the email Using the intercepted email, an attacker could gain access to your site and wreak havoc More Infos This security vulnerability is well-known and has been around for a looong time.
