CVE-2026-45796Network attack vector

Unauthenticated internal reconnaissance via certificate URL fetch

Published Jul 7, 2026 · Updated Jul 7, 2026

SSRF in Coder allows remote attackers to probe internal hosts and ports through its unauthenticated Azure identity endpoint. azureidentity.Validate accepts an untrusted PKCS#7 IssuingCertificateURL, fetches it with http.DefaultClient without destination restrictions, and returns differentiated errors. No account or Azure configuration is required; response bodies stay hidden, but returned errors reveal reachability and internal network details.
