CWE-22 05/06/2026
Path Traversal in Altium Projects Service Allows Arbitrary File Read
A path traversal vulnerability exists in the Projects Service download endpoint shared by Altium Enterprise Server and Altium 365. An authenticated user can supply a crafted path parameter that bypasses validation, allowing arbitrary files (including entire directories returned as archives) to be read from the server filesystem.
Because the readable files include service configuration and credential material, exploitation can be used to gather information enabling further compromise. The issue can be combined with CVE-2026-11424 to reach the cloud-side endpoint. On multi-tenant Altium 365 deployments, the readable configuration could have exposed credentials shared across services. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.

CWE-22 05/06/2026
Path Traversal in Altium Vault ScriptsController Allows Unauthenticated Remote Code Execution
Two endpoints in the Vault Service ScriptsController, shared by Altium Enterprise Server and Altium 365, accept file uploads where a user-supplied filename component is used to construct the destination path without validation, allowing arbitrary files to be written to any location writable by the service account. Because the file write operation completes before authentication is validated, the vulnerability can be exploited without any credentials, session, or prior knowledge of the system.
An unauthenticated network attacker can use this primitive to place executable content in directories where it is later executed by the service, resulting in remote code execution under the Vault Service account. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 (commercial and government cloud) at the service level.

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-22 05/06/2026
Path Traversal in Altium Enterprise Server Collaboration Service Allows Privilege Escalation
A path traversal vulnerability exists in the Altium Enterprise Server Collaboration Service due to improper handling of user-supplied filenames in the MCAD and Simulation file download flows. A regular authenticated user can submit a collaboration message containing a crafted filename, which is later used to construct the download path on the server without validation, allowing arbitrary files to be read from the server filesystem.
Because the readable files include the server's master configuration, which stores credentials for privileged accounts, exploitation can lead to authenticating as a system administrator and gaining full control of the server. Altium 365 cloud deployments are not affected.
CVE-2026-11420

CWE-22 05/06/2026
Path Traversal in Altium Enterprise Server NIS Allows Unauthenticated Arbitrary File Write and File Read
Two path traversal vulnerabilities in the Network Installation Service (NIS) of Altium Enterprise Server allow an unauthenticated network attacker to write arbitrary files to any writable location on the server filesystem and to read package archive files from the server. No authentication, session, or credentials are required.
Because content-controlled files can be written to web-accessible directories, or used to overwrite application binaries or configuration files, exploitation can be escalated to remote code execution in the context of the service account, and can disclose deployment package contents. Altium 365 cloud deployments are not affected, as the Network Installation Service is not part of the cloud offering.

CWE-22 05/06/2026
Path Traversal in Altium Enterprise Server Vault UploadController Allows Arbitrary File Write
A path traversal vulnerability exists in the Altium Enterprise Server Vault Service UploadController due to improper validation of a user-controlled path component in image upload requests. An authenticated user can supply a crafted absolute path so that the configured storage root is discarded, allowing arbitrary files to be written to any location on the server filesystem writable by the service account.
Because content-controlled files can be written to web-accessible directories, or used to overwrite application binaries or configuration files, this can be escalated to remote code execution, service takeover, or denial of service. Altium 365 cloud deployments are not affected, as the affected endpoint is not reachable and the cloud storage architecture mitigates the file-write primitive.

CWE-22 05/06/2026
Unauthenticated File Exfiltration in Altium Enterprise Server Vault Service via Hard-coded Cryptographic Key and Path Traversal
A hard-coded cryptographic key is used by Altium Enterprise Server to sign file download URLs in the Vault service. Because the key is identical across all installations, an unauthenticated network attacker who can reach the server can forge valid download signatures and retrieve files from the Vault storage area without any authentication, session, or credentials.
A separate path traversal vulnerability in the same download endpoint allows the configured storage root to be escaped, enabling reads of arbitrary files on the server filesystem. Combined, these issues allow an unauthenticated attacker to obtain sensitive server configuration and key material, which can lead to full server compromise. The vulnerability can be chained with CVE-2026-9152 to enumerate and bulk-download stored content. Altium 365 cloud deployments are not impacted in practice, as file storage uses object storage rather than the local filesystem.

CWE-306 20/05/2026
Falta de autenticação no SearchService do Altium 365 em endpoint SOAP legado (CWE-306)
Existe uma vulnerabilidade de falta de autenticação no Altium 365 SearchService. Um endpoint SOAP legado expõe operações do índice de busca sem exigir autenticação, tokens de sessão ou qualquer forma de verificação de identidade. Um atacante de rede não autenticado que consiga referenciar o identificador do workspace de um alvo pode interagir com o índice de busca desse workspace, ultrapassando limites entre tenants. A exploração bem-sucedida permite ler o conteúdo indexado de um workspace, como dados de componentes, nomes de projetos e pastas e metadados de usuários, e injetar, modificar ou excluir entradas do índice de busca. Essas operações afetam apenas o índice de busca, não os dados do vault subjacente, mas podem divulgar informações sensíveis do workspace e comprometer a integridade e a disponibilidade dos resultados de busca. Implantações em nuvem do Altium 365 são afetadas; o Altium Enterprise Server local não é afetado.

CWE-22 20/05/2026
Travessia de diretório no StorageController do Altium Enterprise Server permite leitura arbitrária de arquivos
Existe uma vulnerabilidade de travessia de diretório no StorageController do Altium Enterprise Server Viewer devido ao tratamento inadequado de parâmetros de rota de caminhos de arquivo. Em implantações locais que usam armazenamento em sistema de arquivos local, um usuário autenticado comum pode fornecer um caminho absoluto codificado em URL (como uma letra de unidade codificada) em uma requisição à API de armazenamento do Viewer, fazendo com que a raiz de armazenamento configurada seja descartada e permitindo a leitura de arquivos arbitrários do sistema de arquivos do servidor.
Como os arquivos legíveis incluem a configuração mestre do servidor, que armazena credenciais de banco de dados, localizações de chaves de assinatura, senhas de certificados e segredos OAuth, a exploração pode levar à divulgação de todos os segredos do servidor e ao comprometimento total do servidor e de seus dados. Implantações em nuvem não são afetadas, pois usam armazenamento de objetos e não habilitam este componente.

CWE-22 20/05/2026
Path traversal no ComparisonService do Altium Enterprise Server (CVE-2026-9102)
Uma vulnerabilidade de path traversal existe no ComparisonService do Altium Enterprise Server devido à falta de sanitização de nomes de arquivo nas APIs de upload de arquivos Gerber. Um usuário autenticado comum do workspace pode fornecer um nome de arquivo elaborado no cabeçalho Content-Disposition do multipart para escapar do diretório temporário de upload pretendido e gravar arquivos arbitrários em qualquer local do sistema de arquivos do servidor.
Como arquivos controlados pelo conteúdo podem ser gravados em diretórios acessíveis via web, isso pode ser escalado para execução remota de código no contexto da conta de serviço. Também pode ser usado para sobrescrever binários da aplicação ou arquivos de configuração, levando à tomada do serviço ou à negação de serviço.

CWE-284 19/01/2026
Altium 365 Over-Permissive CORS Configuration Allows Credentialed Cross-Origin Workspace Access
Altium 365 workspace endpoints were configured with an overly permissive Cross-Origin Resource Sharing (CORS) policy that allowed credentialed cross-origin requests from other Altium-controlled subdomains, including forum.live.altium.com. As a result, JavaScript executing on those origins could access authenticated workspace APIs in the context of a logged-in user. When chained with vulnerabilities in those external applications, this misconfiguration enables unauthorized access to workspace data, administrative actions, and bypass of IP allowlisting controls, including in GovCloud environments.
