# Essential Real Estate WordPress plugin: free activation of paid listing packages

The Essential Real Estate WordPress plugin before 5.3.5 lets a self-registered customer activate a paid listing package without paying. The site also records a paid invoice at the package's full price.

_Summary, check and fix written by a model from the sources; labelled as such._

## Fix

- Essential Real Estate WordPress plugin: move to `5.3.5` or later

## Timeline

- 2026-11-05T06:31:53+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-90966

## From the sources

The Essential Real Estate WordPress plugin before 5.3.5 does not verify, in one of its AJAX actions, that a listing package selected for free activation is genuinely free or that the requesting user is entitled to it, allowing a self-registered customer to activate a paid package without payment and cause the site to record a paid invoice at the package's full price.
