Gorse: ausência de autenticação nas APIs de dump e restore do banco de dados
O Gorse anterior à versão 0.5.10 contém uma vulnerabilidade de bypass de autenticação nos endpoints /api/dump e /api/restore que permite que atacantes não autenticados acessem funcionalidades protegidas quando admin_api_key está vazio, que é a configuração padrão. Atacantes remotos podem exfiltrar o banco de dados inteiro, incluindo registros de usuários, itens e dados de feedback contendo informações pessoalmente identificáveis, ou sobrescrever completamente o conjunto de dados sem autenticação.

CWE-306 26/06/2026
Budibase: Unauthenticated S3 signed upload URL generation allows arbitrary writes with stored datasource credentials
Budibase is an open-source low-code platform. Prior to 3.39.3, the application server exposes an unauthenticated endpoint that generates S3 PutObject presigned URLs using credentials stored in a workspace datasource. The route is protected only by the recaptcha middleware and does not require authentication, table permission, datasource permission, or builder access. A public caller who knows a workspace ID and S3 datasource ID can request a signed upload URL for attacker-controlled bucket and key values. This vulnerability is fixed in 3.39.3.

CWE-306 25/06/2026
FOSSBilling: Unauthenticated update patcher endpoint allows remote maintenance execution
FOSSBilling is a free, open-source billing and client management system. In versions 0.5.4 through 0.7.2, the /run-patcher maintenance endpoint in FOSSBilling was accessible without authentication, which allowed unauthenticated remote users to trigger update patch routines that modify configuration files, execute database schema changes, perform filesystem mutations, and clear caches. The /run-patcher endpoint executes privileged maintenance operations - configuration migrations, database patch execution (including ALTER TABLE, DROP TABLE, UPDATE statements), filesystem deletions and renames, and cache clearing - without requiring administrator authentication, CSRF validation, or CLI context. An unauthenticated remote attacker can trigger these operations by sending a simple HTTP GET request to /run-patcher, which can be abused for denial-of-service attacks. Certain patches (e.g., batch token regeneration for all admin and client accounts in patch 53, and session invalidation) are disruptive even when re-executed against an already-patched instance. Repeated or concurrent requests may also cause inconsistent database state. This issue has been fixed in version 0.8.0.

CWE-306 25/06/2026
Falta de autenticação em endpoints WebSocket de estações de recarga
Endpoints WebSocket não possuem mecanismos de autenticação adequados, permitindo que atacantes se façam passar por estações de recarga. Como resultado, atacantes podem explorar essa fraqueza para obter acesso não autorizado a dados sensíveis ou executar ações não autorizadas. Como nenhuma autenticação é exigida, isso pode levar a escalada de privilégios e potencialmente comprometer a segurança de todo o sistema.

CWE-306 25/06/2026
LibreChat: 2FA Backup Code Regeneration Without OTP Verification Allows 2FA Bypass
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the POST /api/auth/2fa/backup/regenerate endpoint regenerates all 2FA backup codes without requiring any TOTP token or existing backup code verification. An attacker with a stolen session token can silently replace a victim's backup codes and use them to bypass 2FA login or disable 2FA entirely. This vulnerability is fixed in 0.8.4-rc1.

CWE-306 25/06/2026
LibreChat: 2FA Re-enrollment Allows Full Account 2FA Takeover Without OTP Verification
LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the GET /api/auth/2fa/enable endpoint can be called by an authenticated user (or attacker with a stolen session) even when 2FA is already fully enabled on the account. This endpoint overwrites the existing TOTP secret, generates new backup codes, and sets twoFactorEnabled to false — all without requiring any TOTP or backup code verification. An attacker with a valid session token can completely take over a victim's 2FA, locking the legitimate user out of their own two-factor authentication. This vulnerability is fixed in 0.8.4-rc1.

CWE-306 24/06/2026
SiYuan: Unauthenticated SQLite Data Exfiltration via Template Injection in /api/icon/getDynamicIcon
SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the /api/icon/getDynamicIcon endpoint is explicitly excluded from authentication in SiYuan's kernel router (router.go, "不需要鉴权" -- no auth needed). When called with type=8 and a valid block id parameter, this endpoint invokes RenderDynamicIconContentTemplate, which executes a Go template that includes the querySQL and queryBlocks functions. These functions run arbitrary SELECT statements against the SiYuan SQLite database. An unauthenticated network-adjacent attacker who knows a valid block ID can exfiltrate all user note content, tags, asset references, and block attributes from the database. This vulnerability is fixed in 3.7.0.

Rclone rcd --rc-serve: ausência de autenticação permite execução de comandos (CVE-2026-49980)
Rclone é um programa de linha de comando para sincronizar arquivos e diretórios com diferentes provedores de armazenamento em nuvem. Da versão 1.46.0 até a versão 1.74.3, o rclone rcd --rc-serve aceita requisições GET e HEAD sem autenticação para caminhos na forma: /[remote:path]/object. O valor de remote é extraído da URL e passado para a inicialização normal do backend. A configuração inline de remote pode definir opções de backend que executam comandos locais durante a inicialização. Como resultado, uma única requisição GET ou HEAD sem autenticação pode executar um comando como usuário do processo rclone. Esta vulnerabilidade está corrigida na versão 1.74.3.

Unauthenticated self-registration in MailerUp allows access to stored email data
Missing Authentication for Critical Function (CWE-306) in the RegisterView (apps/accounts/views.py), exposed at POST /api/auth/register/, in MailerUp <1.0.1 allows a remote, unauthenticated attacker to self-register a working account on instances where registration is intended to be restricted, because the endpoint applies the AllowAny permission with no email verification, CAPTCHA, or administrator approval. Any account created this way can read all email stored by the instance, resulting in full disclosure of stored messages to an arbitrary unauthenticated attacker

n8n @n8n/mcp-browser: ausência de autenticação no endpoint MCP HTTP
O n8n é uma plataforma de automação de fluxos de trabalho de código aberto. Antes das versões 2.25.7 e 2.26.2, quando o @n8n/mcp-browser é executado no modo de transporte HTTP, o endpoint MCP aceita solicitações de inicialização de sessão e de invocação de ferramentas sem qualquer autenticação. Qualquer cliente acessível pela rede, ou qualquer site visitado pelo usuário, pode estabelecer uma sessão MCP e invocar ferramentas de controle do navegador. Quando a extensão n8n AI Browser Bridge está instalada e uma conexão com o navegador está ativa, um chamador não autenticado pode acessar recursos de controle do navegador, incluindo navegação, avaliação de JavaScript e acesso a cookies e armazenamento, no perfil real do navegador do usuário. Este problema afeta apenas instâncias em que o @n8n/mcp-browser é executado com o transporte HTTP (--transport http). Esta vulnerabilidade está corrigida nas versões 2.25.7 e 2.26.2.

CWE-306 22/06/2026
Capgo - Missing Authentication Middleware on GET /private/role_bindings Endpoint
Capgo (backend Supabase edge functions) before 12.128.2 does not apply the global authentication middleware to the GET /private/role_bindings/:org_id endpoint, unlike the POST and DELETE role_bindings routes, so unauthenticated requests reach the handler instead of being rejected at the middleware layer. The handler still performs its own authorization check and returns Unauthorized, so no direct data exposure occurs; the flaw is inconsistent authentication enforcement across HTTP methods that could enable authorization bypass if the handler logic changes.

Streamable HTTP mode exposes LINE Desktop read/send tools without MCP authentication
Line Desktop MCP is a project that, while unaffiliated with the official line-bot-mcp-server, allows users to directly operate the LINE Desktop application on Windows or Mac via MCP. `line-desktop-mcp` supports a `--http-mode` Streamable HTTP transport for use with clients such as n8n. In this mode the server binds to `0.0.0.0` and exposes the MCP `/mcp` endpoint without an MCP-layer authentication check. Prior to version 1.1.2, any network client that can reach the port can initialize a session, list tools, and call tools that read LINE Desktop chat history or send LINE messages through the already logged-in desktop application. Version 1.1.2 fixes the issue.
