python: Python: Cross-Site Scripting (XSS) vulnerability in http.cookies module

A flaw was found in Python's http.cookies module. The Morsel.jsoutput function, responsible for generating JavaScript output for cookies, does not properly neutralize the HTML sequence. This oversight could allow a remote attacker to inject malicious script into a web page, potentially leading to...

CVE-2026-9073

A flaw was found in foreman-mcp-server. This component utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers, which are treated as authentication credentials, at an informational level. The other, when debug...

CVE-2026-54761

CVE-2026-54761 – Traefik Kubernetes Gateway crossProviderNamespaces bypass : The issue allows an HTTPRoute outside the allow-listed namespace to expose internal Traefik services (e.g., api@internal, dashboard@internal, rest@internal) via cross-provider TraefikService references when the route use...

CVE-2026-53622

CVE-2026-53622 affects Traefik versions 3.6.17–3.7.1. The vulnerability arises in HTTP/3 (QUIC) TLS configuration selection: the code path GetTLSGetClientInfo() performs an exact, case-sensitive lookup on info.ServerName, failing to match wildcard patterns or mixed-case hostnames. As a result, du...

CVE-2026-53622

Traefik is an HTTP reverse proxy and load balancer. Prior to 3.7.3, there is a critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection that allows unauthenticated clients to bypass router-specific mTLS enforcement. When HTTP/3 is enabled on an entrypoint, the TLS handshake...

CVE-2026-49411

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.8.0, the Node.js compatibility TCP path checked the permission against the original hostname string before resolution and then did not re-check after resolution. A caller could therefore pass a numeric alias of an IP address fo...

CVE-2026-54309

n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, when @n8n/mcp-browser is run in HTTP transport mode, the MCP endpoint accepts session initialization and tool invocation requests without any authentication. Any network-reachable client, or any website visited by the...

CVE-2026-44789

Summary (CVE-2026-44789, n8n): An authenticated user with permission to create/modify workflows can trigger global prototype pollution via an unvalidated pagination parameter in the HTTP Request node, potentially enabling remote code execution on the n8n host. Affected versions: before 1.123.43, ...

CVE-2026-54309

CVE-2026-54309 affects n8n when the MCP Browser is run with HTTP transport. The MCP endpoint accepts session initialization and tool invocation without authentication, enabling unauthenticated callers (including websites visited by the user) to access browser-control tools (navigation, JavaScript...

CVE-2026-55766

guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP. Prior to 2.12.1, guzzlehttp/psr7 did not reject CR/LF characters in certain first-party HTTP start-line fields: the request method, protocol version, and response reason phrase. If an application placed attacker-controlled dat...

CVE-2026-55766

Summary (CVE-2026-55766): guzzlehttp/psr7 (PHP) before 2.12.1 is vulnerable to CRLF injection in the HTTP start-line fields (method, protocol version, reason phrase) when attacker-controlled data ends up in those fields and the message is serialized or forwarded. The flaw requires the malformed m...

CVE-2023-54365

Traefik before 2.10.5 and 3.0.0-beta4 is affected by a denial-of-service vulnerability in HTTP/2 request handling inherited from the Go standard library's HTTP/2 implementation CVE-2023-44487 / CVE-2023-39325, the 'Rapid Reset' technique. A remote attacker can rapidly create and cancel HTTP/2...

JLSEC-2026-621 Thread-safety and out-of-bounds reads in the HTTP.jl content-type sniffer

Description The content-type sniffer had two memory/concurrency bugs. Number sniffing in isjson stored the strtod end-pointer out-parameter in a shared module-global VectorPtrUInt8; concurrent sniff calls on a multithreaded server raced on that single cell between the ccall and the subsequent rea...

JLSEC-2026-613 Redirect credential leakage across scheme/port in HTTP.jl

Description Redirect handling decided whether to retain credential-bearing headers Authorization, Cookie, Proxy-Authorization, etc. by comparing only the hostname, ignoring scheme and port. As a result an https→http downgrade or a same-host/different-port redirect was treated as same-origin and...

JLSEC-2026-623 Insufficient HTTP/2 pseudo-header and Host/:authority validation in HTTP.jl server

Description The HTTP/2 server's request validator passed only :method, :path, and :authority through a normalizer that rejects CR/LF/CTL but permits SP/HTAB and applies no host or token grammar. As a result a :method such as "GET /admin?x=" was accepted, :path could carry interior whitespace, and...

JLSEC-2026-622 Predictable WebSocket masking key and handshake nonce in HTTP.jl client

Description The WebSocket client masking key wssendframe! and the Sec-WebSocket-Key handshake nonce wsrandomhandshakekey were generated with randUInt8, n, which draws from the task-local Xoshiro256++ PRNG. Xoshiro is not cryptographically secure: its internal state can be recovered from a short r...

JLSEC-2026-614 WebSocket default Origin check ignores scheme and port in HTTP.jl

Description The default WebSocket Origin validator originalloweddefault only enforced the host component of the same-origin tuple. It never checked the Origin's scheme, and when the request Host header carried no explicit port the norm for default-port 80/443 servers, where browsers omit the port...

JLSEC-2026-611 Unbounded HTTP/2 concurrent streams and Rapid Reset denial of service in HTTP.jl server

Description The HTTP.jl HTTP/2 server advertised an empty initial SETTINGS frame, leaving SETTINGSMAXCONCURRENTSTREAMS effectively unlimited, and the HEADERS code path allocated per-stream state, a send-window entry, and a Threads.@spawned handler with no check on the number of open streams...

CVE-2023-54365

The CVE covers Traefik versions prior to 2.10.5 and 3.0.0-beta4 affected by a denial-of-service in HTTP/2 request handling derived from the Go standard library’s HTTP/2 implementation (the Rapid Reset technique). A remote attacker can rapidly create and cancel HTTP/2 streams, exhausting server re...
