Description

The click5 CRM add-on to Contact Form 7 WordPress plugin through 1.0.4 does not have authorisation and CSRF checks when updating options via a REST endpoint, and does not ensure that the option to be updated belongs to the click5 CRM add-on to Contact Form 7 WordPress plugin through 1.0.4. As a result, unauthenticated attackers could change arbitrary blog options, allowing them to create a new administrator account and take over the site.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown click5 CRM add-on to Contact Form 7 — Up to and including 1.0.4
