CVE-2026-93579

Red Hat Build of Debezium 3.6 · Vulnerability

CVSS 3.1 6.5 MEDIUMCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-93579

Published

A flaw was found in Netty's HTTP/2 stack. This vulnerability allows a remote attacker to inject prohibited characters, such as NUL, Line Feed, and Carriage Return, into HTTP/2 header field values due to insufficient validation. When these values cross an HTTP/2 to HTTP/1.1 translation boundary, they can be exploited for request smuggling, header injection, or response splitting. This could lead to unauthorized access, data manipulation, or other security bypasses.
