{"cve":"CVE-2026-63645","nvd":{"published":"2026-09-24T18:17:19.053","modified":"2026-10-05T16:17:14.793","status":"Deferred","description":"OpenObserve is a cloud-native observability platform. Prior to 0.90.3, OpenObserve registers the /config/runtime endpoint without authentication and serializes the complete server configuration after applying the hide_sensitive_fields keyword filter. The filter does not recognize dsn or creds field names, so meta_postgres_dsn, meta_postgres_ro_dsn, meta_ddl_dsn, and usage_reporting_creds can be returned in plaintext to an unauthenticated network client. PostgreSQL deployments can expose database credentials, and the same response can disclose the root administrator email address, internal NATS address, filesystem layout, and other deployment details. This issue is fixed in version 0.90.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/openobserve/openobserve/commit/4f3db1cf790ffe8ea065d98f87344e839ec6e477","https://github.com/openobserve/openobserve/pull/12220","https://github.com/openobserve/openobserve/releases/tag/v0.90.3","https://github.com/openobserve/openobserve/security/advisories/GHSA-v496-g5c9-vqxw"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-63645","score":0.00333,"percentile":0.2628,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
