CWE-200 05/06/2026
Server-Side Request Forgery in Altium Platform Design GraphQL Service Allows Information Disclosure
A server-side request forgery (SSRF) vulnerability exists in a GraphQL service component shared by Altium Enterprise Server and Altium 365. An authenticated user can submit a request whose input is treated as a URL by the server and used to issue an outbound HTTP GET request without URL validation or destination filtering. The response body is then returned to the user.
This allows an authenticated attacker to reach internal services and metadata endpoints that would not otherwise be accessible from the public network, and to retrieve their contents. The impact is information disclosure and internal infrastructure reconnaissance; the request primitive is limited to HTTP GET with no custom headers. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.

CWE-200 05/06/2026
async-http-client: Cookie header not stripped on cross-origin redirect
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Versions on the 2.x branch prior to 2.15.0 and the 3.x branch prior to 3.0.10 leak `Cookie` headers to cross-origin redirect targets. When following a redirect to a different origin, the `propagatedHeaders()` method in `Redirect30xInterceptor.java` strips `Authorization` and `Proxy-Authorization` headers but does not strip the `Cookie` header, causing session cookies and other sensitive cookie values to be sent to attacker-controlled servers. Versions 2.15.0 and 3.0.10 patch the issue.

CWE-200 05/06/2026
HAX CMS: exposição de chave privada por implementação HMAC defeituosa
HAX CMS ajuda a gerenciar um universo de microsites com backends em PHP ou NodeJs. Antes da versão 26.0.0, a função `hmacBase64()` no backend Node.js do HAXcms contém dois erros críticos de implementação criptográfica que, juntos, permitem que qualquer atacante não autenticado extraia a chave privada de assinatura do sistema e forje JSON Web Tokens (JWTs) com privilégios de administrador, obtendo acesso administrativo total com uma única requisição HTTP. Primeiro, a função passa a string literal "0" como chave de assinatura HMAC, em vez do parâmetro key, o que faz com que todas as instâncias do HAXcms calculem HMACs idênticos para a mesma entrada. Em seguida, após calcular o HMAC, a função concatena diretamente na saída o parâmetro key real, que é "this.privateKey + this.salt", o segredo mestre de assinatura do sistema. O buffer combinado é codificado em base64 e retornado como token. Todo token base64url produzido tem a mesma estrutura: 32 bytes de HMAC com chave "0" seguidos de N bytes de `privateKey+salt`. Um atacante decodifica em base64 qualquer token, descarta os primeiros 32 bytes e lê a chave privada diretamente. O endpoint `/system/api/connectionSettings` não exige autenticação e retorna vários tokens gerados por essa função. Uma única requisição GET a esse endpoint expõe a chave privada. O backend PHP implementa essa função corretamente, com a chave real, e retorna apenas o hash. A versão PHP produz tokens de 44 caracteres, enquanto a versão Node.js defeituosa produz tokens de 139 ou mais caracteres. A versão 26.0.0 corrige o problema.

Strawberry GraphQL: Default GraphiQL may expose HTTP headers in URLs
Strawberry GraphQL is a library for creating GraphQL APIs. In versions 0.288.4 through 0.315.3, Strawberry's bundled GraphiQL template wrote values from the GraphiQL headers editor into the browser URL query string. If a user entered a sensitive header, such as `Authorization: Bearer <token>`, the value could become visible in browser history, copied links, and server/proxy/CDN access logs after a page reload or shared request. Version 0.315.4 patches the issue.

MISP Dashboard widget field selection may expose restricted user and organisation data
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields.
For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response.
The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields.
Impact:
An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.

CWE-200 04/06/2026
Unauthorized exposure of private galaxies in MISP event template creation
A visibility control issue in the event template creation workflow allowed non-site-admin users to access private galaxies belonging to other organisations. The event template builder loaded all enabled galaxies without applying organisation or distribution-based access restrictions, potentially exposing private galaxy metadata such as galaxy type and description to users who should not have visibility.
The issue has been fixed by restricting galaxy queries for non-site-admin users to galaxies owned by the user’s organisation or galaxies with a non-private distribution setting. Site administrators retain visibility of all enabled galaxies.

FOSSBilling version exposed via asset cache buster
FOSSBilling is a free, open-source billing and client management system. Versions prior to 0.8.0 leak the exact system version through asset cache buster parameters in HTML output, bypassing the `hide_version_public` security setting. The FOSSBilling version is embedded in the query string of every `<script>` and `<link>` tag generated by the `script_tag` and `stylesheet_tag` Twig filters. This information is visible to all visitors — including unauthenticated guests — on every page, regardless of whether the `hide_version_public` setting is enabled. The `X-FOSSBilling-Version` HTTP header and the `guest.system.version` API endpoint correctly honour the `hide_version_public` setting, but the asset cache buster parameters were overlooked. Knowledge of the exact FOSSBilling version makes it significantly easier for malicious actors to identify known vulnerabilities applicable to a given installation and craft targeted exploits. While not a direct vulnerability on its own, it undermines the intended protection offered by the `hide_version_public` setting and facilitates reconnaissance. Version 0.8.0 contains a patch. There is no practical workaround that removes the version from asset URLs without modifying source code.

LibreChat: injeção de placeholders em URL de servidor MCP vaza segredos do servidor
LibreChat é um clone aprimorado do ChatGPT que oferece suporte a múltiplos provedores de IA. Nas versões até e incluindo 0.8.3, a integração com servidores do Model Context Protocol (MCP) resolve placeholders ${VAR} com base no process.env do servidor durante a validação de esquema Zod de URLs de servidores MCP informadas pelo usuário. Qualquer usuário autenticado pode criar uma configuração maliciosa de servidor MCP com URL apontando para um domínio controlado pelo atacante contendo referências a variáveis de ambiente, fazendo o servidor LibreChat conectar-se ao servidor do atacante e transmitir segredos críticos como CREDS_KEY, CREDS_IV, JWT_SECRET e MONGO_URI na URL da requisição. Isso permite comprometimento total dos materiais criptográficos da instalação e das credenciais de banco de dados, sem exigir privilégios administrativos. Isto foi corrigido na versão 0.8.4-rc1.
