CVE-2026-73494

blaze is a Scala library for asynchronous network I/O pipelines. Five HTTP/1.1 conformance laxities in its hand-written Java parser (http/src/main/java/org/http4s/blaze/http/parser/) accept malformed requests—invalid tchar header names, obs-fold lines, unsupported Transfer-Encoding values, duplic...

CVE-2026-73494 blaze: Multiple HTTP/1.1 request-smuggling primitives in blaze's Java wire parser

blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. Prior to 0.23.18 and from 1.0.0-M1 until 1.0.0-M42, five HTTP/1.1 conformance laxities in the hand-written Java parser under http/src/main/java/org/http4s/blaze/http/parser/ can cause blaze to derive a...

Astra Linux – Vulnerability in libmysofa

Incorrect handling of input data in the verifyAttribute function in the libmysofa library version 0.5 to 1.1 may lead to NULL pointer dereferencing and segmentation faults in cases of restrictive memory protection, or NULL pointer overwriting in cases where no memory restrictions exist e.g., in...

Astra Linux – Vulnerability in Jetty9

In Eclipse Jetty, the HTTP/1.1 parser is vulnerable to request smuggling when chunk extensions are used, similar to the “funky chunks” techniques described here: https://w4ke.info/2025/06/18/funky-chunks.html https://w4ke.info/2025/10/29/funky-chunks-2.html Jetty terminates the chunk extension...

Astra Linux – Vulnerability in Twisted

Twisted is an event-based framework for internet applications, compatible with Python 3.6+. Before version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the twisted.web.http module, parsed several HTTP request constructs more leniently than allowed by RFC 7230. This non-conformant parsin...

CVE-2026-73494: Inconsistent Interpretation of HTTP Requests

blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. Prior to 0.23.18 and from 1.0.0-M1 until 1.0.0-M42, five HTTP/1.1 conformance laxities in the hand-written Java parser under http/src/main/java/org/http4s/blaze/http/parser/ can cause blaze to derive a...

CVE-2026-90678

An issue was discovered in HAProxy 3.3.0 through 3.4.4 and in 3.5-dev1 through 3.5-dev5. Exploitation requires an HTTP/3 frontend: HAProxy must be built with QUIC support and configured with a QUIC bind listener, and the affected traffic must reach a backend over HTTP/1.1 using chunked transfer...

curl: HTTP/1.1 response framing violation and unsafe connection reuse when transfer decoding is disabled

Summary: libcurl can incorrectly reuse an HTTP/1.1 connection after a response containing both Content-Length and a non-chunked Transfer-Encoding when transfer decoding is disabled with CURLOPTHTTPTRANSFERDECODING = 0L --raw behavior. In this state, libcurl can treat Content-Length as the respons...

SUSE CVE-2026-19203

A client may issue specially crafted HTTP/1.1 chunked requests to a Jetty server that cause Jetty and an intermediary proxy to interpret different request boundaries, potentially resulting in HTTP request smuggling. This is caused by Jetty accepting a lone LF character as a terminator in parts of...

GHSA-W4V4-9RW7-5326 Traefik: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') and Incorrect Authorization

Summary There is a high-severity request-smuggling vulnerability in Traefik's handling of the HTTP/1.1 Upgrade mechanism. Since Traefik moved to unencrypted HTTP/2 with prior knowledge Go 1.24, a client-initiated Upgrade: h2c request header and its connection-specific HTTP2-Settings header were...

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...

PT-2026-89511

Name of the Vulnerable Software and Affected Versions Puma versions 5.0.0 through 8.0.2 Description An issue exists that allows an attacker to execute arbitrary code via the ext/puma http11/http11 parser.rl file. Recommendations Update Puma to version 8.0.3 or later...

Security Bulletin: undici does not validate the type property of a duck-typed blob-like request body before using it as the Content-Type header on the HTTP/1.1 dispatcher

Summary Upgrade to InformixHQ 3.3.2 Vulnerability Details CVEID:CVE-2026-15157 DESCRIPTION: undici does not validate the type property of a duck-typed blob-like request body before using it as the Content-Type header on the HTTP/1.1 dispatcher. In undici before 6.28.0, from 7.0.0 up to before...

undici: undici: HTTP response splitting via retry interceptor

A flaw was found in undici. An attacker-controlled upstream server can exploit a vulnerability in the retry interceptor, which incorrectly appends data to a ranged retry response. This can cause the response body to be longer than the Content-Length observed by the application. Consequently, an...

HTTPX2: Conflicting Content-Length and Transfer-Encoding headers can be auto-generated

Summary HTTPX2 can automatically add a Content-Length header to a request that already contains a caller-supplied Transfer-Encoding header. The resulting HTTP/1.1 request contains both framing headers, which can create an ambiguous message boundary and enable request smuggling or connection...
