Email manipulation via SMTP header injection
Published Sep 29, 2025 · Updated Feb 26, 2026
SMTP header injection in VMware vCenter Server before 7.0 U3w or 8.0 U3g allows remote authenticated users to alter task emails. Broadcom has not disclosed the input field, code locus, or missing neutralization step that permits attacker-controlled data to enter generated SMTP headers. Exploitation requires non-administrative vCenter privileges and permission to create scheduled tasks; the reported consequence is manipulation of resulting notification emails.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=7.0 <7.0 U3w
- Affected versionversion=8.0 <8.0 U3g
