Vulnerability Insight:
The following vulnerabilities exist:

- Authors could alter meta data to delete files that they weren't authorized to.

- Authors could create posts of unauthorized post types with specially crafted input.

- Contributors could craft meta data in a way that resulted in PHP object injection.

- Contributors could edit new comments from higher-privileged users, potentially leading to a cross-site scripting vulnerability.

- Specially crafted URL inputs could lead to a cross-site scripting vulnerability in some circumstances.
WordPress itself was not affected, but plugins could be in some situations.

- The user activation screen could be indexed by search engines in some uncommon configurations,
leading to exposure of email addresses, and in some rare cases, default generated passwords.

- Authors on Apache-hosted sites could upload specifically crafted files that bypass MIME verification,
leading to a cross-site scripting vulnerability.

Affected Software/OS:
All versions since WordPress 3.7 up to 5.0.

The issues have been fixed in version 5.0.1.
Updated versions of WordPress 4.9 and older releases are also available.
