CVE-2026-39361 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in OpenObserve versions through 0.14.5. The issue arises in the 'validate_enrichment_url' function, which fails to properly validate IPv6 addresses due to the way Rust's 'url' crate formats them, enclosing them in brackets. This oversight allows authenticated attackers to access internal services that are normally restricted from external access. In cloud deployments, this could lead to unauthorized retrieval of IAM credentials from AWS, GCP, or Azure. On self-hosted deployments, it could enable probing of internal network services.
Users are advised to update to the latest version of OpenObserve, where this vulnerability has been addressed.
