Vulnerability from fkie_nvd - Published: 2026-10-12 22:17 - Updated: 2026-10-13 21:17
Severity
9.3 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H
Summary
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.
