CVE-2026-73495

blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. Prior to 0.23.18 and 1.0.0-M42, 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...

jetty: Eclipse Jetty: Information disclosure due to retained HTTP/1.1 trailers across connections

A flaw was found in Eclipse Jetty. This vulnerability allows a remote attacker to cause the server to retain HTTP/1.1 request trailers from a prior connection. Consequently, subsequent requests made over the same connection may unintentionally disclose information by reporting the previously...

CVE-2026-65624

The CVE affects the Cowboy HTTP/1.1 handler. The root cause is a per-request header handling flaw: when a request uses repeated header names, values are concatenated into a single binary under one map key, so the max_headers limit never increases and the total header block can grow without bound....

SUSE CVE-2025-57804

h2 is a pure-Python implementation of a HTTP/2 protocol stack. Prior to version 4.3.0, an HTTP/2 request splitting vulnerability allows attackers to perform request smuggling attacks by injecting CRLF characters into headers. This occurs when servers downgrade HTTP/2 requests to HTTP/1.1 without...
