Summary

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.

Risk Assessment

An attacker can gain full control of the WordPress site by creating an admin account and modifying settings, potentially leading to integrity and availability compromise.

Recommendation

Update the click5 CRM add-on to Contact Form 7 to the latest patched version. Additionally, restrict access to REST endpoints and implement additional authorization mechanisms.
