Executive Summary

CVE-2026-25393 is a Broken Access Control vulnerability found in the WordPress Hello FSE Theme versions up to and including 1.0.6.

The issue arises from missing authorization, authentication, or nonce token checks within certain functions of the theme.

This allows unprivileged users to perform actions that should be restricted to higher-privileged roles such as Subscribers or Developers.

It is classified under the OWASP Top 10 category A1: Broken Access Control.

Impact Analysis

This vulnerability allows unauthorized users to perform actions reserved for privileged roles, potentially leading to unauthorized changes or access within the WordPress site.

Although the CVSS severity score is 4.3, indicating a low impact and priority, exploitation could still compromise site integrity or functionality.

No official patch is available, and the theme has not been updated for over a year, making it unlikely to receive fixes.

Deactivating the theme alone does not eliminate the risk unless a mitigation rule from Patchstack is applied.

Recommended mitigation includes removing and replacing the vulnerable theme or deploying Patchstack’s mitigation rules.
