CVE-2026-126065: OpenObserve authentication bypass with empty password

CVE-2026-126065 · Severity: critical · CVSS 9.8 · Published 2026-11-10

OpenObserve is a cloud-native platform for monitoring and analyzing telemetry data from applications and infrastructure. An attacker who knows a user's email address can bypass authentication on API routes by submitting an empty password, impersonating that user with their full permissions. Attackers can then read or modify monitoring data, security settings, and user accounts, or execute arbitrary code by uploading files to the server.

Technical details

The authentication validator in validator.rs accepts empty or whitespace-only HTTP Basic passwords when a user's password_ext field is missing or empty, a state that can occur for SSO-provisioned or migration-created accounts. An unauthenticated attacker with knowledge of a target user's email and organization can authenticate to protected non-ingestion API routes with the victim's role and permissions. Escalation to remote code execution is possible via a DataFusion COPY statement in the search API from an account with search permissions.
