CVE-2026-4792 (GCVE-0-2026-4792)

Vulnerability from cvelistv5 – Published: 2026-09-19 07:43 – Updated: 2026-09-19 14:01

Title

Bread <= 2.9.12 - Missing Authorization to Unauthenticated Information Exposure

Summary

The Bread plugin for WordPress is vulnerable to information exposure in versions up to and including 2.9.12. This is due to the lack of authentication and authorization checks on the settings export functionality (download_settings function) which is registered on the plugins_loaded hook and explicitly allows execution on non-admin (public) pages. The function exports all plugin configuration settings including the protection_password field, which is stored in plaintext. This makes it possible for unauthenticated attackers to retrieve the PDF protection password by accessing the /?export-meeting-list=1 endpoint.

Severity
