0 CVE-2026-107566 is a missing authorization vulnerability in Progressive Robot Ltd's hMailServer affecting versions 6.0.0 through 6.3.6. It allows an authenticated user to manipulate email headers via the Sieve editheader action or mail-rule Set header value action to send emails appearing from any address at a domain the server signs for, including DKIM-signed messages. This can result in forged emails that align with the domain's DMARC policy. The vulnerability impacts the integrity of email sending by permitting header modifications without proper authorization.
