CWE-287 22/05/2026
RT: LDAP authentication bypass via empty password
RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.9 and prior in addition to 6.0.0 through 6.0.2 contain an authentication bypass vulnerability in RT installations that use LDAP/AD for user authentication. Under certain LDAP server configurations, an attacker may be able to authenticate as any LDAP-backed RT user without supplying valid credentials. This issue has been fixed in versions 5.0.10 and 6.0.3. If developers are unable to upgrade immediately, they can temporarily work around this issue by reviewing their LDAP server's authentication policy to ensure it rejects unauthenticated bind attempts. Upgrading RT remains the recommended fix.

CWE-287 22/05/2026
TypeBot: WhatsApp Webhook Endpoint Missing Signature Verification
TypeBot is a chatbot builder tool. In versions 3.16.0 and prior, the WhatsApp Cloud API webhook endpoint (POST /v1/workspaces/{workspaceId}/whatsapp/{credentialsId}/webhook) does not verify the x-hub-signature-256 HMAC signature included by Meta in every webhook delivery. The webhook URL exposes both workspaceId and credentialsId as path parameters, which are logged in web server access logs, visible in Meta's webhook configuration dashboard, and potentially shared when configuring integrations. This allows any unauthenticated attacker to send spoofed webhook messages to trigger bot flows, consume API resources, and interact with external services using the workspace owner's credentials. The issue has been fixed in version 3.17.0.

Sunshine: bypass de autenticação por validação imprópria de certificado de cliente
O Sunshine é um host self-hosted de streaming de jogos para o Moonlight. Nas versões anteriores a 2026.516.143833, a autenticação por certificado de cliente pode ser contornada devido à forma como os resultados de verificação do OpenSSL são tratados. No arquivo src/crypto.cpp, o callback de verificação personalizado trata X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY, X509_V_ERR_CERT_NOT_YET_VALID e X509_V_ERR_CERT_HAS_EXPIRED como sucesso. Isso pode permitir que um certificado não confiável passe pela autenticação e acesse endpoints HTTPS protegidos. Este problema foi corrigido na versão 2026.516.143833.

MISP OIDC authentication bypass via automatic email-based account linking under insecure IdP configurations
MISP’s OIDC authentication plugin allowed automatic linking of an OIDC identity to an existing local user account based on the email claim when the local account had no stored sub value. Under insecure or untrusted IdP configurations where email ownership is not enforced, an attacker with a valid OIDC token could assert a victim’s email address and authenticate as that user, leading to account takeover.

Account Switcher <= 1.0.2 - Authenticated (Subscriber+) Authentication Bypass to Privilege Escalation
The Account Switcher plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0.2. This is due to the `rememberLogin` REST API endpoint using a loose comparison (`!=` instead of `!==`) for secret validation at `app/RestAPI.php:111`, combined with no validation that the secret is non-empty. When a target user has never used the "Remember me" feature, their `asSecret` user meta does not exist, causing `get_user_meta()` to return an empty string. An attacker can send an empty `secret` parameter, which passes the comparison (`'' != ''` is `false`), and the endpoint then calls `wp_set_auth_cookie()` for the target user. Additionally, all REST routes use `permission_callback => '__return_true'` with no capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to switch to any user account including Administrator, ultimately granting themselves full administrative privileges.

Open WebUI: bypass de autenticação LDAP com senha vazia
O Open WebUI é uma plataforma de inteligência artificial de autohospedagem, projetada para operar totalmente offline. Antes da versão 0.9.0, o endpoint de autenticação LDAP não valida se a senha enviada não está vazia antes de executar um Simple Bind no servidor LDAP. O modelo Pydantic LdapForm aceita password: str sem restrição de tamanho mínimo, de modo que uma string vazia passa na validação. A chamada subsequente Connection.bind() tem sucesso em servidores LDAP vulneráveis, e a aplicação emite um token de sessão completo para o usuário alvo. Esta vulnerabilidade é corrigida na versão 0.9.0.

Form Notify para WordPress – Bypass de Autenticação via Callback OAuth do LINE
O plugin Form Notify para WordPress é vulnerável a Bypass de Autenticação nas versões até e incluindo 1.1.10. Isso ocorre porque o plugin confia em dados de cookie controlados pelo usuário para determinar qual conta WordPress deve ser autenticada após um login OAuth do LINE. Quando o LINE não fornece um endereço de e-mail (o que é comum), o plugin recorre ao valor do cookie 'form_notify_line_email' sem verificar se a conta LINE está associada a esse endereço. Isso torna possível que atacantes não autenticados ganhem acesso a qualquer conta de usuário do site, incluindo contas de administrador, ao concluir um fluxo OAuth do LINE com a própria conta LINE enquanto injetam um cookie malicioso contendo o endereço de e-mail da vítima.

Cisco Catalyst SD-WAN Controller Authentication Bypass Vulnerability
May 2026: This security advisory provides the details and fix information for a vulnerability that was discovered and fixed after the was disclosed in February 2026. This new advisory is for a new vulnerability in the control connection handshaking. The section of this advisory includes Show Control Connections guidance to help with system checks.
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 the 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.

Plugin Burst Statistics para WordPress - Bypass de Autenticação com Tomada de Conta Administrativa
O plugin Burst Statistics – Privacy-Friendly WordPress Analytics (Google Analytics Alternative) para WordPress é vulnerável a Bypass de Autenticação nas versões 3.4.0 a 3.4.1.1. Isso se deve a tratamento incorreto do valor de retorno na função is_mainwp_authenticated() ao validar senhas de aplicação do cabeçalho Authorization. Isso torna possível que atacantes não autenticados, conhecendo o nome de usuário de um administrador, se passem por esse administrador durante a requisição fornecendo qualquer senha aleatória de Basic Authentication, alcançando escalonamento de privilégios.

fast-jwt: segredo HMAC vazio aceito em resolvedor de chaves assíncrono (bypass de autenticação JWT)
fast-jwt fornece uma implementação rápida de JSON Web Tokens (JWT). Antes da versão 6.2.4, uma vulnerabilidade crítica de bypass de autenticação no fluxo de resolvedor de chaves assíncrono do fast-jwt permite que qualquer atacante não autenticado forje JWTs arbitrários que são aceitos como autênticos. Quando o resolvedor de chaves da aplicação retorna uma string vazia (''), por exemplo por meio do fallback estilo JWKS keys[decoded.header.kid] || '', o fast-jwt a converte em um Buffer de comprimento zero, a passa para crypto.createSecretKey, deriva allowedAlgorithms = ['HS256','HS384','HS512'] a partir dela e então verifica a assinatura do token contra um HMAC com chave vazia. O atacante simplesmente calcula HMAC-SHA256(key='', input='${header}.${payload}'), que o Node aceita sem reclamar, e o verificador retorna o payload escolhido pelo atacante (sub, admin, scopes etc.) como autêntico. Esta vulnerabilidade está corrigida na versão 6.2.4.

ChurchCRM: Incomplete fix for CVE-2026-40582: public API login still bypasses 2FA and account lockout in ChurchCRM 7.2.2
ChurchCRM is an open-source church management system. From 7.2.0 to 7.2.2, The fix for CVE-2026-4058 is incomplete. The hardening commit was merged and then silently stripped from src/api/routes/public/public-user.php by an unrelated PR before any 7.2.x tag was cut. Every shipped 7.2.x release therefore remains exploitable by the PoC published with the original advisory. This vulnerability is fixed in 7.3.1.
