      <title>CVE-2026-39361 — OpenObserve has a SSRF Protection Bypass via IPv6 Bracket Notation in validate_enrichment_url</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-39361</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; openobserve&lt;/p&gt;
&lt;p&gt;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&amp;#39;s url crate returns them with surrounding brackets (e.g. &amp;#34;[::1]&amp;#34; not &amp;#34;::1&amp;#34;). 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.&lt;/p&gt;</description>
