CVE-2026-93574

CVE-2026-93574 affects Netty's netty-codec-http component, where an incorrect parsing of HTTP/1.1 chunk-size tokens containing post-digit whitespace enables HTTP request smuggling . A remote attacker with no privileges can exploit this over the network to bypass security controls or access unauth...

CVE-2026-93574 Io.netty/netty-codec-http: netty: http request smuggling via post-digit whitespace in chunk-size parsing

A flaw was found in Netty's netty-codec-http component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an...
