WordPress Core is vulnerable to Information Disclosure of in versions up to 6.0.3. When the post by email functionality is enabled, it may log post author's email addresses in a way that may be publicly accessible.

This could make it possible for attackers to steal post author's email addresses and use that for further attacks.

Not sure which version you run? Run a passive check — it reads public files only.
