EUVD-2026-42082

GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the parsecontentrange function within src/http.c that allows server-controlled values to cause signed integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigg...

CVE-2026-58470

GNU Wget 1.25.0 and earlier is affected by an integer overflow in parse_content_range() (src/http.c) triggered by server-controlled Content-Range headers, leading to undefined behavior and download desynchronization. The issue is fixed in commit 43d3ba9, and users should upgrade to a version that...

PYSEC-2026-1427 Connection confusion in gRPC

When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this...

Name of the Vulnerable Software and Affected Versions GNU Wget versions prior to 1.25.0 commit 43d3ba9 Description An integer overflow occurs in the parse content range function within src/http.c. This issue allows server-controlled values to cause signed integer arithmetic to overflow. An attack...

haproxy: HAProxy: Response smuggling due to integer overflow in FastCGI record length handling

A flaw was found in HAProxy. A malicious FastCGI Fast Common Gateway Interface backend can exploit an integer overflow vulnerability in the fcgiconn structure's drl field. This occurs when specific contentLength and paddingLength values cause the drl field to wrap to zero, leading to incorrect...

CVE-2026-38969

A flaw was found in WEBrick, a Ruby web server toolkit. This vulnerability allows a remote attacker to perform request smuggling by manipulating the Content-Length header in HTTP/1.1 requests. WEBrick incorrectly re-parses the trailer Content-Length, leading to a desynchronization between the pro...

CVE-2026-48743

A flaw was found in Envoy, an open source edge and service proxy. This vulnerability occurs when Envoy translates an HTTP/3 request that is complete at the transport layer but still carries a nonzero Content-Length into an HTTP/1 request for an upstream server. If the upstream server responds...

BIT-HAPROXY-2026-33555

An issue was discovered in HAProxy before 3.3.6. The HTTP/3 parser does not check that the received body length matches a previously announced content-length when the stream is closed via a frame with an empty payload. This can cause desynchronization issues with the backend server and could be...

CVE-2026-55603

A flaw was found in http-proxy-middleware. A remote attacker could exploit a vulnerability in the fixRequestBody function, which is used to re-emit a request body. By injecting carriage return and line feed characters \r\n into a request body key or value, an attacker can bypass security policies...

BIT-HAPROXY-2026-55203 HAProxy - Integer Overflow in FCGI Demux Record Length Field

HAProxy through 3.4.0, fixed in commit 5985276, contains an integer overflow vulnerability in the fcgiconn structure's drl field that allows buffer misparse as new FCGI record headers. When contentLength is 65535 and paddingLength is 1 or more, the drl field wraps to 0, causing incorrect record...

CVE-2026-47206

Dragonfly is an in-memory store. Before version 1.39.9, it is vulnerable to RESP protocol injection via Lua redis.error_reply() in EvalSerializer, allowing an authenticated user to inject arbitrary RESP messages into the connection’s response stream and potentially desynchronize responses for con...

CVE-2026-47206 Dragonfly: RESP Protocol Injection via Lua redis.error_reply() in EvalSerializer

Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.39.9, Dragonfly has a RESP Protocol Injection via Lua redis.errorreply in EvalSerializer. An authenticated user can inject arbitrary RESP messages into the connection's response stream, potentially causing...

Astra Linux – Vulnerability in Erlang

Inconsistent interpretation of HTTP requests: The “HTTP Request Smuggling” vulnerability in Erlang OTP inets httpd module allows for HTTP requests to be disguised. This vulnerability is associated with the program file lib/inets/src/httpserver/httpdrequest.erl and the routine...

JLSEC-2026-624 HTTP/2 client HPACK desynchronization via header blocks for unknown streams in HTTP.jl

Description The HTTP/2 client's processincomingframe! dropped HEADERS/CONTINUATION frames for stream ids absent from conn.streams without passing the header block through the connection's HPACK decoder. Because HPACK's dynamic table is connection-scoped and mutated as a side effect of decoding ea...

CVE-2026-55603

http-proxy-middleware is node.js http-proxy middleware. From 3.0.4 until 3.0.7 and 4.1.1, fixRequestBody is the library's documented helper for re-emitting a request body that was already consumed by a body parser. When the outgoing Content-Type is multipart/form-data, it rebuilds the body with...
