CVE-2026-85121

Summary

The Insurify WordPress plugin lacks proper authorization and nonce checks on an AJAX endpoint, allowing unauthenticated attackers to modify critical WordPress options and potentially take sites offline. This vulnerability enables arbitrary configuration changes that can deactivate the plugin and disrupt site functionality.

Exploitability

Exploitation is straightforward requiring only a single HTTP request to the vulnerable AJAX endpoint with crafted parameters, with no prerequisites for authentication or additional conditions.

Blast radius

The impact could affect all WordPress sites using Insurify plugin version 1.0, potentially causing widespread service disruption and plugin deactivation across multiple installations.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the affected AJAX endpoint immediately or upgrade to version 2.590 or later if available, otherwise implement a temporary workaround by restricting access to the vulnerable endpoint via .htaccess rules.
