Published Sep 24, 2026CWE-200EPSS 0.33%

Overview

CVE-2026-63645 is a high-severity vulnerability. It was published on September 24, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
