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.
