0 CVE-2026-34975 is a high-severity CRLF injection vulnerability in the open-source email platform plunk (useplunk) versions prior to 0.8.0. The flaw allows authenticated API users to inject arbitrary email headers by embedding carriage return and line feed characters in certain user-supplied fields such as from.name, subject, custom header keys/values, and attachment filenames. This can lead to silent email forwarding, reply redirection, or sender spoofing. The vulnerability is fixed in version 0.8.0 by adding input validation to reject these characters in the affected fields. The platform is cloud-hosted, and the vendor manages remediation for the service. Join the discussion | CVE Database V5 | 04/06/2026, 16:10:05 UTC Added: 04/06/2026, 16:30:32 UTC |
