CWE-287 12/03/2026
Tinyauth vulnerable to TOTP/2FA bypass via OIDC authorize endpoint
Tinyauth is an authentication and authorization server. Prior to 5.0.3, the OIDC authorization endpoint allows users with a TOTP-pending session (password verified, TOTP not yet completed) to obtain authorization codes. An attacker who knows a user's password but not their TOTP secret can obtain valid OIDC tokens, completely bypassing the second factor. This vulnerability is fixed in 5.0.3.

AdGuard Home: bypass de autenticação via upgrade h2c em texto claro
AdGuard Home é um software de rede para bloqueio de anúncios e rastreamento. Antes da versão 0.107.73, um atacante remoto não autenticado pode contornar toda a autenticação do AdGuardHome enviando uma requisição HTTP/1.1 que solicita upgrade para HTTP/2 em texto claro (h2c). Uma vez aceito o upgrade, a conexão HTTP/2 resultante é tratada pelo mux interno, que não tem middleware de autenticação associado. Todas as requisições HTTP/2 subsequentes nessa conexão são processadas como totalmente autenticadas, independentemente de credenciais terem sido fornecidas. Esta vulnerabilidade está corrigida na versão 0.107.73.

Neo4j Enterprise Edition: autenticação inadequada com múltiplos provedores SSO habilitados
Um caso limite na implementação de SSO no Neo4j Enterprise Edition, nas versões anteriores à 2026.02, pode levar a acesso não autorizado nas seguintes condições:
Se um administrador do neo4j configurar dois ou mais provedores OIDC E configurar um ou mais deles como provedor de autorização E configurar um ou mais deles como somente autenticação, então aqueles configurados somente para autenticação também fornecerão autorização. Esse caso limite só se torna um problema de segurança se o provedor somente de autenticação contiver grupos com privilégios superiores aos fornecidos pelo provedor de autorização pretendido (configurado).
Ao usar múltiplos plugins para autenticação e autorização, antes da correção o problema podia levar a um plugin configurado para fornecer apenas capacidades de autenticação ou de autorização fornecer ambas as capacidades por engano.
Recomendamos atualizar para as versões 2026.02 (ou 5.26.22), nas quais o problema foi corrigido.

CWE-287 10/03/2026
Parse Server OAuth2 authentication adapter account takeover via identity spoofing
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.9. and 8.6.22, the OAuth2 authentication adapter, when configured without the useridField option, only verifies that a token is active via the provider's token introspection endpoint, but does not verify that the token belongs to the user identified by authData.id. An attacker with any valid OAuth2 token from the same provider can authenticate as any other user. This affects any Parse Server deployment that uses the generic OAuth2 authentication adapter (configured with oauth2: true) without setting the useridField option. This vulnerability is fixed in 9.5.2-alpha.9. and 8.6.22.

CWE-287 10/03/2026
Parse Server is missing audience validation in Keycloak authentication adapter
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.5 and 8.6.18, the Keycloak authentication adapter does not validate the azp (authorized party) claim of Keycloak access tokens against the configured client-id. A valid access token issued by the same Keycloak realm for a different client application can be used to authenticate as any user on the Parse Server that uses the Keycloak adapter. This enables cross-application account takeover in multi-client Keycloak realms. All Parse Server deployments that use the Keycloak authentication adapter with a Keycloak realm that has multiple client applications are affected. This vulnerability is fixed in 9.5.2-alpha.5 and 8.6.18.

Feathers: contorno de autenticação no callback OAuth leva à tomada de conta
Feathersjs é um framework para criar APIs web e aplicações em tempo real com TypeScript ou JavaScript. Das versões 5.0.0 até antes de 5.0.42, um atacante não autenticado pode enviar uma requisição GET elaborada diretamente para /oauth/:provider/callback com um perfil forjado na query string. A cadeia de fallback do payload de autenticação do serviço OAuth alcança params.query (a query bruta da requisição) quando as respostas de sessão/state do Grant estão vazias. Como o atacante nunca iniciou um fluxo de autorização OAuth, o Grant não tem sessão com que trabalhar e não produz resposta, então o fallback é acionado. O perfil forjado então direciona a busca de entidade e a emissão de JWT. O atacante obtém um token de acesso válido para um usuário existente sem nunca contatar o provedor OAuth. Esta vulnerabilidade está corrigida na 5.0.42.

Tutor LMS Pro <= 3.9.5 - Authentication Bypass via Social Login
The Tutor LMS Pro plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 3.9.5 via the Social Login addon. This is due to the plugin failing to verify that the email provided in the authentication request matches the email from the validated OAuth token. This makes it possible for unauthenticated attackers to log in as any existing user, including administrators, by supplying a valid OAuth token from their own account along with the victim's email address.

FreshRSS has an authentication bypass due to truncated bcrypt hash [edge branch]
FreshRSS is a free, self-hostable RSS aggregator. From 57e1a37 - 00f2f04, the lengths of the nonce was changed from 40 chars to 64. password_verify() is currently being called with a constructed string (SHA-256 nonce + part of a bcrypt hash) instead of the raw user password. Due to bcrypt’s 72-byte input truncation, this causes password verification to succeed even when the user enters an incorrect password. This vulnerability is fixed in 1.27.2-dev (476e57b). The issue was only present in the edge branch and never in a stable release.

Rocket.Chat: 2FA bypass and login of deactivated users via EE ddp-streamer
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0, authentication vulnerabilities exist in Rocket.Chat's enterprise DDP Streamer service. The Account.login method exposed through the DDP Streamer does not enforce Two-Factor Authentication (2FA) or validate user account status (deactivated users can still login), despite these checks being mandatory in the standard Meteor login flow. This issue has been patched in versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0.

Rocket.Chat: Users can login with any password via the EE ddp-streamer-service
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0, a critical authentication bypass vulnerability exists in Rocket.Chat's account service used in the ddp-streamer micro service that allows an attacker to log in to the service as any user with a password set, using any arbitrary password. The vulnerability stems from a missing await keyword when calling an asynchronous password validation function, causing a Promise object (which is always truthy) to be evaluated instead of the actual boolean validation result. This may lead to account takeover of any user whose username is known or guessable. This issue has been patched in versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0.

OneUptime has WebAuthn 2FA bypass: server accepts client-supplied challenge instead of server-stored value, allowing credential replay
OneUptime is a solution for monitoring and managing online services. In version 10.0.11 and prior, the WebAuthn authentication implementation does not store the challenge on the server side. Instead, the challenge is returned to the client and accepted back from the client request body during verification. This violates the WebAuthn specification (W3C Web Authentication Level 2, §13.4.3) and allows an attacker who has obtained a valid WebAuthn assertion (e.g., via XSS, MitM, or log exposure) to replay it indefinitely, completely bypassing the second-factor authentication. No known patches are available.

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.

OpenClaw 2026.1.14-1 < 2026.2.2 - Allowlist Bypass via displayName and Cross-Homeserver localpart Matching in Matrix Plugin
OpenClaw version 2026.1.14-1 prior to 2026.2.2, with the Matrix plugin installed and enabled, contain a vulnerability in which DM allowlist matching could be bypassed by exact-matching against sender display names and localparts without homeserver validation. Remote Matrix users can impersonate allowed identities by using attacker-controlled display names or matching localparts from different homeservers to reach the routing and agent pipeline.
