CVE-2026-44828

Qexo initialization endpoint can reset setup state and expose stored credentials

Published Oct 12, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
Qexo is an open source online editor for static blogs. From 4.0.0 until 4.2.0, Qexo exposes /api/init_step/ through init_step_api without authentication, authorization, or a setup-completion guard. An unauthenticated requester with a valid CSRF token obtained from a public page can submit the first initialization step and reset the INIT setting, causing the instance to re-enter the setup flow. The setup response and /init/ page can expose stored PROVIDER configuration, including service credentials, in frontend content. This issue is fixed in version 4.2.0.
