CVE-2026-4792
At a glance
CVE-2026-4792 is a medium-severity Missing Authorization vulnerability in the Bread WordPress plugin, affecting versions <= 2.9.12. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.9.13; sites on affected versions should update now. Disclosed September 2026, reported by Itthidej Aramsri (Boeing777).
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in Bread <= 2.9.12 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Bread the fix is 2.9.13: builds <= 2.9.12 are affected, anything from 2.9.13 onward is not.
Remediation
Update to version 2.9.13, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Bread 2.9.13 closes this, and updating the plugin is the step that ends it.
