CWE-346 30/06/2026
Vibe-Trading < 0.1.10 - Loopback Trust and Missing Host Validation Enable DNS-Rebinding Authentication Bypass and Remote Code Execution
Vibe-Trading before 0.1.10 contains a DNS rebinding authentication bypass vulnerability that allows remote attackers to bypass bearer-token authentication by exploiting the server's trust of TCP peer addresses for loopback clients combined with missing Host header validation while binding to 0.0.0.0 with credentialed CORS. Attackers can craft a malicious DNS rebinding page to issue authenticated requests to the local API server, reach the shell execution endpoint with a bash-enabled preset, and achieve remote code execution as the API process user while also overwriting LLM and data-source settings to exfiltrate credentials.

Glances: XML-RPC Server Missing Host Header Validation Enables DNS Rebinding Attack
Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server (glances -s, implemented in glances/server.py) does not validate the HTTP Host header, leaving it vulnerable to DNS rebinding attacks. An attacker can exploit DNS rebinding to exfiltrate the full system monitoring dataset from a victim's browser. This vulnerability is fixed in 4.5.5.

pnpm: manifest identity spoof satisfies allowBuilds and runs attacker lifecycle
pnpm is a package manager. Prior to 10.34.2 and 11.5.3, the generic peer-suffix normalizer also stripped parenthesized text from git, URL, tarball, file, and other opaque locators. Approval for one source string could therefore authorize a different attacker-controlled source whose locator normalized to the same value. This vulnerability is fixed in 10.34.2 and 11.5.3.

LibreChat: roubo de tokens OAuth em MCP por falta de validação do parâmetro resource
O LibreChat é um clone aprimorado do ChatGPT que oferece suporte a múltiplos provedores de IA. Antes da versão 0.8.5, a implementação de OAuth para MCP do LibreChat não valida se o parâmetro resource dos metadados de OAuth Protected Resource (RFC 9728) corresponde à URL do servidor MCP configurado, permitindo que um servidor MCP malicioso roube tokens de acesso destinados a um servidor legítimo. Esta vulnerabilidade está corrigida na versão 0.8.5.

SiYuan Note: falha na validação de origem permite acesso administrativo por extensões do navegador
SiYuan é um sistema de gerenciamento de conhecimento pessoal de código aberto. Antes da versão 3.7.0, o servidor HTTP do kernel do SiYuan Note confia incondicionalmente em todas as origens chrome-extension://, concedendo acesso RoleAdministrator a todas as extensões instaladas no navegador, sem qualquer autenticação. Combinado com o AccessAuthCode padrão vazio nas instalações desktop, qualquer extensão do Chrome/Chromium — incluindo uma extensão legítima comprometida por meio de um ataque à cadeia de suprimentos — pode fazer chamadas administrativas totalmente autenticadas à API do kernel do SiYuan em 127.0.0.1:6806, possibilitando exfiltração de dados, injeção de XSS armazenado e adulteração de configurações. Esta vulnerabilidade está corrigida na versão 3.7.0.

CWE-346 23/06/2026
Open WebUI: Cross-origin postMessage confirmation bypass via action:submit
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, the chat message listener allows non-same-origin input:prompt and action:submit messages, so an external site can set prompt text and trigger submitPrompt() in an authenticated victim session. I validated this with a cross-origin attacker page that auto-posted messages and caused unauthorized POST /api/v1/chats/new and POST /api/chat/completions requests containing attacker-controlled prompts. This enables cross-site forced actions and model/tool execution under victim privileges without consent. This vulnerability is fixed in 0.9.6.

CWE-346 23/06/2026
Guzzle: Dot-Only Cookie Domains Match All Hosts in guzzlehttp/guzzle
Guzzle is an extensible PHP HTTP client. Prior to 7.12.1, CookieJar incorrectly accepts cookies with a dot-only Domain attribute and whitespace-padded variants. SetCookie::matchesDomain() removes leading dots from the cookie domain, normalizing dot-only values to the empty string; SetCookie::validate() only rejected a strictly empty domain, so these cookies could be stored and the empty normalized domain was treated as matching any request host. An attacker-controlled origin that an application requests with a shared cookie jar can therefore set a cookie that Guzzle later sends to unrelated hosts using the same jar. This may allow cookie injection or session fixation against downstream services, depending on how those services interpret the injected cookie. This vulnerability is fixed in 7.12.1.

Angular: URL Parser Differential in @angular/platform-server leading to SSRF Allowlist Bypass
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23, an issue in the @angular/platform-server package allows remote attackers to bypass host allowlist constraints and direct server-side outgoing requests to arbitrary external endpoints. This occurs due to a parser differential between the strict WHATWG URL parser used for allowlist validation and the lenient Domino URL parser used to initialize the server emulated DOM. When a server-side request contains a malformed URL with a double port structure (e.g., http://evil.com:80:80/path), Node's strict URL.canParse(url) logic returns false and skips host check validation entirely. However, the same malformed URL is later accepted and parsed leniently by Domino's internal parser, which resolves the origin to http://evil.com:80. The Angular SSR HTTP request interceptor (relativeUrlsTransformerInterceptorFn) then resolves all relative backend HTTP requests against this adopted origin, executing the SSRF attack. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.

CWE-346 22/06/2026
Apache NiFi: Missing Validation for Proxy Host Headers
Apache NiFi 0.0.1 through 2.9.0 support building qualified URLs from one of several HTTP request headers that provide an alternative to the standard Host header without validating the values provided. Apache NiFi 1.6.0 introduced a configurable application property to restrict values provided in the HTTP Host header, but did not apply the validation to alternative Proxy and Forwarded headers. The absence of proxy host header validation allowed a client to instruct Apache NiFi web services to construct invalid qualified URLs for redirection or data references. Upgrading to Apache NiFi 2.10.0 is the recommended mitigation, which implements validation for the X-ProxyHost and X-Forwarded-Host HTTP request headers based on the nifi.web.proxy.host property. Enabling header validation requires configuring the application with HTTPS. Reverse proxy servers in front of Apache NiFi are responsible for filtering input request headers and providing allowed values to the application.

CWE-346 17/06/2026
undici vulnerable to cross-origin request routing via SOCKS5 proxy pool reuse
Impact:
When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless of the intended destination.
This causes cross-origin request routing: credentials and request data intended for origin B are sent to origin A, responses from the wrong origin are trusted, and HTTPS requests may be silently downgraded to HTTP.
Impacted users are applications that use Socks5ProxyAgent (directly or via setGlobalDispatcher) and make requests to more than one origin.
This was introduced in undici 7.23.0 via PR #4385 and affects all versions through 8.1.0.
Patches:
Upgrade to undici v7.26.0 or v8.2.0.
Workarounds:
Use a separate Socks5ProxyAgent instance per origin, or avoid using Socks5ProxyAgent with multiple origins.

CWE-346 15/06/2026
webpack-dev-server vulnerable to HMR WebSocket interception via permissive user proxies
Impact: When a user-configured proxy on webpack-dev-server has a broad context (e.g. /) and ws: true, it also intercepts the dev server's own HMR WebSocket and forwards it to the proxy target. This leaks the browser's cookies and Origin header to the backend, bypasses the dev server's Host/Origin validation, and corrupts the HMR socket (both HMR and the proxy end up writing to the same socket).
Patches: Fixed in webpack-dev-server@5.2.5.
Workarounds: Scope user-defined proxy context to specific paths instead of /, or omit ws: true from the proxy entry when WebSocket forwarding is not required.

The Model Context Protocol has a security warning advising servers to validate the "Origin" header on all incoming connections to prevent DNS rebinding attacks. Prior to the v0.25.0 release, users had no way to validate the origin's host. In v0.25.0, a new "--allowed-hosts" flag was introduced alongside the existing "--allowed-origins" flag, enabling users to specify permitted hosts at server startup. Both flags default to "*", allowing users to implement strict access controls as needed without breaking existing setups. If either flag is set to "*", the server will output a startup warning about potential vulnerabilities. Documentation has also been updated to highlight these security considerations.
