CVE-2026-39361

Estado: AnalizadaAlta (7.7)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:L: explotación remota autenticada → T1210. El bypass del filtrado de IPv6 permite SSRF (T1090) hacia servicios internos; en cloud, acceso a IAM credentials vía IMDS (T1552.005).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

En despliegues en la nube, esto permite la recuperación de credenciales IAM a través de AWS IMDSv1 (169.254.169.254), metadatos de GCP o Azure IMDS. En despliegues autoalojados, permite el sondeo de servicios de red internos."
