Talishar: Authentication Bypass via Empty authKey Parameter Allows Unauthenticated Game Actions
Talishar is a fan-made Flesh and Blood project. Prior to commit a9c218e, an authentication bypass vulnerability in Talishar's game endpoint validation logic allows any unauthenticated attacker to perform authenticated game actions — including sending chat messages and submitting game inputs — by supplying an empty authKey parameter (authKey=). The server-side validation uses a loose comparison that accepts an empty string as a valid credential, while correctly rejecting non-empty but incorrect keys. This asymmetry means the authentication mechanism can be completely bypassed without knowing any valid token. This issue has been patched in commit a9c218e.

OpenEMR: divulgação de token MedEx sem autenticação
OpenEMR é um aplicativo gratuito e de código aberto para prontuários eletrônicos de saúde e gestão de práticas médicas. Antes da versão 8.0.0, uma vulnerabilidade de divulgação de token não autenticada no endpoint de callback da MedEx permite que qualquer visitante não autenticado obtenha os tokens de API da MedEx da clínica, levando ao comprometimento completo de serviços de terceiros, exfiltração de PHI, ações não autorizadas na plataforma MedEx e violações da HIPAA. A vulnerabilidade existe porque o endpoint ignora a autenticação ($ignoreAuth = true) e executa um login na MedEx sempre que $_POST['callback_key'] é fornecido, retornando a resposta JSON completa, incluindo tokens de API sensíveis. Esta vulnerabilidade está corrigida na versão 8.0.0.

WeGIA lacks authentication verification in adicionar_tipo_docs_atendido.php
WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, the script in adicionar_tipo_docs_atendido.php does not go through the project's central controller and does not have its own authentication and permission checks. A malicious user could make a request through tools like Postman or the file's URL on the web to access features exclusive to employees. The vulnerability allows external parties to inject unauthorized data in massive quantities into the application server's storage. Version 3.6.5 fixes the issue.

Japanized for WooCommerce <= 2.8.4 - Missing Authorization to Unauthenticated Paidy Order Manipulation
The Japanized for WooCommerce plugin for WordPress is vulnerable to Improper Authentication in versions up to, and including, 2.8.4. This is due to a flawed permission check in the `paidy_webhook_permission_check` function that unconditionally returns `true` when the webhook signature header is omitted. This makes it possible for unauthenticated attackers to bypass payment verification and fraudulently mark orders as "Processing" or "Completed" without actual payment via a crafted POST request to the Paidy webhook endpoint.

Discourse doesn't ensure webhooks require a token
Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, several webhook endpoints (SendGrid, Mailjet, Mandrill, Postmark, SparkPost) in the `WebhooksController` accepted requests without a valid authentication token when no token was configured. This allowed unauthenticated attackers to forge webhook payloads and artificially inflate user bounce scores, potentially causing legitimate user emails to be disabled. The Mailpace endpoint had no token validation at all. Starting in versions 2025.12.2, 2026.1.1, and 2026.2.0, all webhook endpoints reject requests with a 406 response when no authentication token is configured. As a workaround, ensure that webhook authentication tokens are configured for all email provider integrations in site settings (e.g., `sendgrid_verification_key`, `mailjet_webhook_token`, `postmark_webhook_token`, `sparkpost_webhook_token`). There's no current workaround for mailpace before getting this fix.

Cisco Catalyst SD-WAN Controller and Manager Authentication Bypass Vulnerability
A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system.
This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to an affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.

Sentry: autenticação inadequada no SAML SSO permite vinculação de identidades de usuários
O Sentry é uma ferramenta de rastreamento de erros e monitoramento de desempenho voltada para desenvolvedores. As versões 21.12.0 até 26.1.0 apresentam uma vulnerabilidade crítica em sua implementação de SAML SSO, que permite a um invasor assumir qualquer conta de usuário usando um Identity Provider SAML malicioso e outra organização na mesma instância do Sentry. Usuários de instalações self-hosted só correm risco se o seguinte critério for atendido: ore than one organizations are configured, ou seja, mais de uma organização configurada (SENTRY_SINGLE_ORGANIZATION = True), ou um usuário malicioso já tem acesso e permissões para modificar configurações de SSO de outra organização em uma instância multi-organização. Este problema foi corrigido na versão 26.2.0. Como solução alternativa, implemente autenticação de dois fatores baseada na conta do usuário para impedir que um invasor consiga concluir a autenticação com a conta de uma vítima. Administradores de organização não podem fazer isso em nome do usuário; cada usuário precisa garantir que o 2FA esteja habilitado na própria conta.

Strimzi: All CAs from a custom CA chain consisting of multiple CAs are trusted for mTLS user autentication
Strimzi provides a way to run an Apache Kafka cluster on Kubernetes or OpenShift in various deployment configurations. In versions 0.49.0 through 0.50.0, when using a custom Cluster or Clients CA with a multistage CA chain consisting of multiple CAs, Strimzi incorrectly configures the trusted certificates for mTLS authentication on the internal as well as user-configured listeners. All CAs from the CA chain will be trusted. And users with certificates signed by any of the CAs in the chain will be able to authenticate. This issue affects only users using a custom Cluster or Clients CA with a multistage CA chain consisting of multiple CAs. It does not affect users using the Strimzi-managed Cluster and Clients CAs. It also does not affect users using custom Cluster or Clients CA with only a single CA (i.e., no CA chain with multiple CAs). This issue has been fixed in version 0.50.1. To workaround this issue, instead of providing the full CA chain as the custom CA, users can provide only the single CA that should be used.
