{"id":"CVE-2026-39361","state":"PUBLISHED","title":"OpenObserve has a SSRF Protection Bypass via IPv6 Bracket Notation in validate_enrichment_url","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.","publishedAt":"2026-04-07T19:02:12.816Z","updatedAt":"2026-04-09T16:17:46.139Z","severity":{"score":7.7,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["openobserve openobserve"],"affected":[{"vendor":"openobserve","product":"openobserve","versions":[{"version":"<= 0.70.3","status":"affected"}]}],"references":["https://github.com/openobserve/openobserve/security/advisories/GHSA-gcwf-3p7h-wm79","https://github.com/openobserve/openobserve/commit/d1a5d8f65b432e2e82f83231390dec7f107e8d75"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/39xxx/CVE-2026-39361.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-39361","state":"PUBLISHED","datePublished":"2026-04-07T19:02:12.816Z","dateUpdated":"2026-04-09T16:17:46.139Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-06T21:29:17.349Z"},"containers":{"cna":{"title":"OpenObserve has a SSRF Protection Bypass via IPv6 Bracket Notation in validate_enrichment_url","descriptions":[{"lang":"en","value":"OpenObserve is a cloud-native observability platform.
