7.7 · HIGHOverview
CVE-2026-39361 is a high-severity vulnerability affecting openobserve openobserve. It was published on April 7, 2026 and has a CVSS 3.1 base score of 7.7 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
OpenObserve is a cloud-native observability platform. In 0.70.3 and earlier, the validate_enrichment_url function in src/handler/http/request/enrichment_table/mod.rs fails to block IPv6 addresses because Rust's url crate returns them with surrounding brackets (e.g. "[::1]" not "::1"). An authenticated attacker can reach internal services blocked from external access. On cloud deployments this enables retrieval of IAM credentials via AWS IMDSv1 (169.254.169.254), GCP metadata, or Azure IMDS. On self-hosted deployments it allows probing internal network services.
Remediation
Check the references section for vendor advisories and patches from openobserve. Update openobserve to the latest patched version. 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.
