CVE-2026-50197

Summary: CVE-2026-50197 affects zalando/skipper’s OpenPolicyAgent integration. When clients use HTTP/1.1 Transfer-Encoding: chunked or HTTP/2 without Content-Length, the opaAuthorizeRequestWithBody flow exposes an empty raw_body and parsed input.parsed_body to OPA, causing policy checks that rely...

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...

Apache2 - Transfer-Encoding Chunked XSS

Apache2 PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 contain a reflected cross-site scripting vulnerability caused by mishandling of chunked transfer-encoding requests in sapi/apache2handler/sapiapache2.c. Attackers can execute malicious scripts via crafted...

CVE-2026-44982

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...

CVE-2026-44982 affects CrowdSec AppSec. The bug in pkg/appsec/request.go NewParsedRequestFromRequest reads the body using max(r.ContentLength, 0), causing HTTP/1.1 chunked and HTTP/2 without Content-Length to appear with an empty body, bypassing body-inspection rules (REQUEST_BODY, BODY_ARGS, ARG...

EEF-CVE-2026-59249 Sign-tolerant HTTP/1 chunk-size parser in Mint enables response smuggling against strict intermediaries on pooled connections

Summary 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...

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-2026-58229 Unbounded HTTP/1 response-header and chunked-trailer accumulation in Mint causes memory-exhaustion DoS

Allocation of resources without limits vulnerability in elixir-mint mint allows a remote HTTP server to exhaust memory on the client host and cause a denial of service. The Mint.HTTP1.decodeheaders/5 and Mint.HTTP1.decodetrailerheaders/4 functions in lib/mint/http1.ex accumulate every parsed...
