Detailsinfo

A vulnerability was found in OpenObserve up to 0.70.3. It has been declared as critical. This vulnerability affects the function validate_enrichment_url of the file src/handler/http/request/enrichment_table/mod.rs. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-39361 since 04/06/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are known technical details, but no exploit is available.

Applying the patch d1a5d8f65b432e2e82f83231390dec7f107e8d75 is able to eliminate this problem. The bugfix is ready for download at github.com.
