CVE-2026-93576 Io.netty/netty-codec-smtp: netty netty-codec-smtp — smtp command-name field is not crlf-validated (incomplete fix of cve-2025-59419)

A flaw was found in Netty netty-codec-smtp. The component does not properly validate Carriage Return CR and Line Feed LF characters in the SMTP command-name field. A remote attacker, if an application routes untrusted input into this field, can embed CR/LF characters to inject arbitrary SMTP...

CVE-2026-93576

CVE-2026-93576 affects Netty netty-codec-smtp , where the SMTP command-name field is not properly CRLF-validated . This is classified as an incomplete fix of the earlier CVE-2025-59419 , meaning the previous remediation did not fully address the validation gap. The Red Hat-assigned CVSS 3.1 score...
