CVE-2026-66753 tiny-http 0.12.0 HTTP Response Splitting via Header Injection

tiny-http through 0.12.0 contains an HTTP header injection vulnerability that allows attackers to inject carriage return 0x0D and line feed 0x0A bytes into HTTP header values on both request and response sides due to insufficient validation in header parsing and serialization. Attackers can explo...

CVE-2026-57511: Improper Neutralization of CRLF Sequences

SuperPlane before 0.30.0 contains an SMTP header injection vulnerability that allows unauthenticated attackers to inject arbitrary SMTP headers by including CRLF sequences in the event payload title field delivered via webhook. Attackers can manipulate the unsanitized title field passed to the SM...

Name of the Vulnerable Software and Affected Versions Rouille versions 0.4.0 through 3.6.2 Description An HTTP response splitting issue exists where remote attackers can inject arbitrary response headers by embedding carriage return 0x0D or line feed 0x0A bytes into input they control. This can...

CVE-2026-59921: Improper Neutralization of CRLF Sequences

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, HttpPostRequestEncoder constructs multipart HTTP request bodies by directly concatenating user-supplied filenames and field names into Content-Disposition MIME headers without...

CVE-2026-59900

A flaw was found in Netty's netty-codec-http2 component. The HTTP/2 encoder does not properly handle special characters in HTTP headers. This vulnerability allows a remote attacker to craft specific HTTP/2 requests, leading to HTTP response splitting and header injection attacks. Such attacks can...

HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling in the process that merges HTTP/1.1 chunked-body trailer fields into Request.headers. An attacker can inject arbitrary HTTP headers by sending specially crafted trailer fields, potentially bypassing header-based...

GHSA-46Q4-43PH-C6FR blaze: Chunked-body trailer fields promoted into Request.headers in blaze-server (front-end header-sanitization bypass)

Summary blaze-server can merge HTTP/1.1 chunked-body trailer fields into Request.headers. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject arbitrary header names/values e.g. X-Forwarded-For, internal-auth headers that a fronting proxy sanitized from the...
