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.","published":"2026-10-12T22:17:04.000Z","lastModified":"2026-10-16T20:04:30.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-538"],"affected":[],"epss":{"score":0.00355,"percentile":0.28931,"date":"2026-10-26","history":[{"date":"2026-10-13","score":0.00355,"percentile":0.27351}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%).
