CVE-2026-39399: CWE-20: Improper Input Validation in NuGet NuGetGalleryCVE-2026-39399 0 CVE-2026-39399 is a critical vulnerability in the NuGetGallery backend job that processes . nuspec files within NuGet packages. The flaw arises from improper input validation of package metadata, enabling attackers to inject malicious metadata via crafted . nuspec files. Exploitation involves URI fragment injection through unsanitized package identifiers, allowing arbitrary blob writes within the storage container beyond intended . nupkg files. This can lead to remote code execution and tampering with existing content. The vulnerability affects versions prior to commit 0e80f87628349207cdcaf55358491f8a6f1ca276. A patch addressing this issue has been committed, mitigating the risk. Join the discussion | CVE Database V5 | 04/14/2026, 23:01:38 UTC Added: 04/14/2026, 23:16:56 UTC |
