What is CVE-2026-0767?
CVE-2026-0767 is a rejected CVE ID: its record was withdrawn on September 2, 2026 and no longer describes a vulnerability. Reason given: Open WebU's investigation showed that this describes the behavior of plain HTTP rather than a defect in the product. TLS termination is the operator's deployment decision, as it is for any backend that speaks HTTP, and not a security issue.https://docs.openwebui.com/security/vendor-dispositions/cve-2026-0767/">https://docs.openwebui.com/security/vendor-dispositions/cve-2026-0767
