{"id":"CVE-2026-126065","kind":"vulnerability","aliases":["CVE-2026-126065"],"related":[],"title":"OpenObserve: empty Basic-auth password accepted, letting attackers log in as users","description":"OpenObserve is a cloud-native observability platform. Prior to 1.1.0, the shared authentication validator in src/api/common/src/auth/validator.rs accepts an empty or whitespace-only HTTP Basic password for an account whose password_ext value is missing or empty. SSO-provisioned and migration-created users can have this state, allowing an unauthenticated attacker who knows an affected user's email address and organization to authenticate on protected non-ingestion API routes with the victim's role and permissions. A compromised privileged account can expose or modify telemetry, alerts, streams, users, and security configuration. An account with search permission can submit a DataFusion COPY ... TO statement through the search API to create or overwrite attacker-controlled files at service-process-writable locations, creating a conditional escalation to pre-authentication remote code execution. This issue is fixed in version 1.1.0.","summary":"OpenObserve accepts an empty or whitespace-only HTTP Basic password for accounts whose stored password_ext is missing or empty, which happens with SSO-provisioned and migrated users.
