CVE-2026-28753

Опубликовано: 24 мар. 2026
Источник: ubuntu
Приоритет: medium
CVSS3: 3.7

Описание

NGINX Plus and NGINX Open Source have a vulnerability in the ngx_mail_smtp_module module due to the improper handling of CRLF sequences in DNS responses. This allows an attacker-controlled DNS server to inject arbitrary headers into SMTP upstream requests, leading to potential request manipulation. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
