CVE-2026-66338: Inconsistent Interpretation of HTTP Requests
A flaw was found in libsoup. The chunked transfer encoding parser uses a permissive parsing function for chunk sizes that silently accepts inputs violating RFC 9112, including leading whitespace, plus sign prefixes, and trailing invalid characters. When libsoup operates behind a strict frontend...

CVE-2026-50197 Skipper: opaAuthorizeRequestWithBody filter bypasses OPA policy on Transfer-Encoding: chunked / HTTP/2 requests
Skipper is an HTTP router and reverse proxy for service composition. Prior to 0.26.10, zalando/skipper's OpenPolicyAgent integration silently bypasses request-body inspection on HTTP/1.1 Transfer-Encoding: chunked and HTTP/2 requests that omit the content-length pseudo-header, because the...

CVE-2026-59249
Inconsistent interpretation of HTTP requests HTTP response smuggling vulnerability in elixir-mint mint allows a malicious HTTP/1 server to desynchronize a strict intermediary and the Mint client on the same pooled connection, enabling response-queue poisoning against subsequent requests that shar...
CVE-2026-59249 Sign-tolerant HTTP/1 chunk-size parser in Mint enables response smuggling against strict intermediaries on pooled connections

CVE-2026-59249
The CVE concerns the Elixir Mint library (mint) and its HTTP/1.1 decoding path. Specifically, Mint.HTTP1.decode_body/5 parses chunk-size lines using Integer.parse(data, 16), which accepts a leading + or - despite RFC 7230 requiring unsigned hex digits. This leads to a mismatch with RFC-strict int...
CVE-2026-44982: Protection Mechanism Failure
CrowdSec offers crowdsourced protection against malicious IPs. From 1.5.0 until 1.7.8, pkg/appsec/request.go NewParsedRequestFromRequest allocated a request body buffer from maxr.ContentLength, 0, so HTTP/1.1 requests using Transfer-Encoding: chunked and HTTP/2 requests without a content-length...
netty: io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to improper handling of conflicting HTTP/1.0 headers
A flaw was found in Netty's HttpObjectDecoder. A remote attacker can exploit this by sending a specially crafted HTTP/1.0 request that includes both Transfer-Encoding: chunked and Content-Length headers. While Netty correctly strips the conflicting Content-Length header for HTTP/1.1 messages, thi...

HTTP Request Smuggling
Overview Affected versions of this package are vulnerable to HTTP Request Smuggling via the ExtractHttpBodyOptionally helper in filters/openpolicyagent/openpolicyagent.go. An attacker can bypass opaAuthorizeRequestWithBody policy checks by sending a chunked HTTP/1.1 request or an HTTP/2 request...
Gunicorn HTTP Request/Response Smuggling vulnerability
Gunicorn version 21.2.0 does not properly validate the value of the 'Transfer-Encoding' header as specified in the RFC standards, which leads to the default fallback method of 'Content-Length,' making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data...
