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.","epss":{"date":"2026-11-13","percentile":0.69282,"score":0.01226},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"}],"kev":null,"metrics":[{"score":9.8,"severity":"critical","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":9.8,"severity":"critical","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794625485343,"publishedAt":1794342034680,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openobserve/openobserve/pull/15054"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openobserve/openobserve/commit/46678ea8daba94c3904286471794f80c5a74ecea"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openobserve/openobserve/commit/dc5c657002d97e9e29726cefcadec49cae755e1a"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/openobserve/openobserve/releases/tag/v1.1.0"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/openobserve/openobserve/commit/46678ea8daba94c3904286471794f80c5a74ecea"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/openobserve/openobserve/commit/dc5c657002d97e9e29726cefcadec49cae755e1a"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/openobserve/openobserve/pull/15054"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/openobserve/openobserve/releases/tag/v1.1.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"},{"source":"GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v"}],"remediation":[{"kind":"fix","source":"GitHub GHSA-7w4v-2c9r-q94v","text":"openobserve (other): GitHub reports patched versions 1.1.0.
