{"id":"CVE-2026-126065","summary":"OpenObserve: Empty external password allows authentication bypass","details":"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.","aliases":["GHSA-7w4v-2c9r-q94v"],"modified":"2026-11-11T10:47:54.229560904Z","published":"2026-11-10T20:20:34.680Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126065.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-287"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126065.json"},{"type":"FIX","url":"https://github.com/openobserve/openobserve/commit/46678ea8daba94c3904286471794f80c5a74ecea"},{"type":"FIX","url":"https://github.com/openobserve/openobserve/commit/dc5c657002d97e9e29726cefcadec49cae755e1a"},{"type":"FIX","url":"https://github.com/openobserve/openobserve/pull/15054"},{"type":"WEB","url":"https://github.com/openobserve/openobserve/releases/tag/v1.1.0"},{"type":"ADVISORY","url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126065"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openobserve/openobserve","events":[{"introduced":"0"},{"fixed":"ed07b6e287da91b0a2d7be8dd061599200e0cd15"},{"fixed":"46678ea8daba94c3904286471794f80c5a74ecea"},{"fixed":"dc5c657002d97e9e29726cefcadec49cae755e1a"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"1.1.0"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"46678ea8daba94c3904286471794f80c5a74ecea"}]},{"range":[{"fixed":"dc5c657002d97e9e29726cefcadec49cae755e1a"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"ed07b6e287da91b0a2d7be8dd061599200e0cd15"}],"source":"REFERENCES_TAG","original_tag":"v1.1.0"}]}}],"versions":["v1.1.0-rc1","v1.0.0-rc1","v0.92.0-rc3","v0.92.0-rc1","v0.91.0-rc2","v0.91.0-rc1","v0.80.0-rc4","v0.80.0-rc1","v0.70.0-rc1","v0.60.0-rc1","v0.50.0-rc1","v0.40.0-rc1","v0.30.0-rc1","v0.20.0-rc1","v0.16.0-rc1","v0.15.0","v0.15.0-rc5","v0.15.0-rc3","v0.15.0-rc2","v0.15.0-rc1","v0.14.7","v0.14.6","v0.14.6-rc7","v0.14.6-rc8","v0.14.6-rc6","v0.14.6-rc5","v0.14.6-rc4","v0.14.6-rc3","v0.14.6-rc2","v0.14.6-rc1","v0.14.5","v0.14.5-rc6","v0.14.5-rc5","v0.14.5-rc4","v0.14.5-rc3","v0.14.5-rc2","v0.14.5-rc1","v0.14.4","v0.14.3","v0.14.3-rc3","v0.14.3-rc2","v0.14.3-rc1","v0.14.2","v0.14.1","v0.14.1-rc3","v0.14.1-rc2","v0.14.1-rc1","v0.14.0","v0.13.2-rc4","v0.13.2-rc3","v0.13.2-rc2","v0.13.2-rc1","v0.13.1","v0.13.1-rc3","v0.13.1-rc2","v0.13.1-rc1","v0.13.0","v0.13.0-rc2","v0.13.0-rc1","v0.12.1","v0.12.0","v0.12.0-rc2","v0.12.0-rc1","v0.11.0","v0.11.0-rc3","v0.11.0-rc2","v0.11.0-rc1","v0.10.9","v0.10.9-rc4","v0.10.9-rc3","v0.10.9-rc2","v0.10.9-rc1","v0.10.8","v0.10.8-rc5","v0.10.8-rc4","v0.10.8-rc3","v0.10.8-rc2","v0.10.8-rc1","v0.10.7","v0.10.7-rc3","v0.10.7-rc2","v0.10.7-rc1","v0.10.6","v0.10.6-rc2","v0.10.6-rc1","v0.10.5","v0.10.4","v0.10.3","v0.10.2","v0.10.2-rc1","v0.10.1","v0.10.0","v0.9.2-rc1","v0.9.1","v0.9.0-rc8","v0.9.0-rc7","v0.9.0-rc6","v0.9.0-rc5","v0.9.0-rc4","v0.9.0-rc3","v0.9.0-rc2","v0.9.0-rc1","v0.8.2-rc7","v0.8.2-rc6","v0.8.2-rc5","v0.8.2-rc4","v0.8.2-rc3","v0.8.2-rc2","v0.8.2-rc1","v0.8.1","v0.8.1-rc2","v0.8.1-rc1","v0.8.0","v0.8.0-rc2","v0.8.0-rc1","v0.7.2-rc1","v0.7.2","v0.7.0","v0.7.0-rc2","v0.7.0-rc1","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.3.2","v0.3.1","v0.3.0","v0.2.0","v0.1.8","v0.1.7","v0.1.6","v0.1.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-126065.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
