CVE-2026-55962 Média · 6.5 CWE-287 25/06/2026
TLS 1.3 post-handshake authentication: server accepts Finished without client Certificate/CertificateVerify
TLS 1.3 post-handshake authentication (PHA) issue where a server could accept a client's Finished message without the client having sent a Certificate and CertificateVerify. The post-handshake-auth exemption that allows an empty/absent peer certificate was only intended for the initial handshake, but it was also being applied while a post-handshake CertificateRequest was still outstanding. The check is now scoped to the initial handshake only: on the server, once a post-handshake CertificateRequest has been sent (certReqCtx is set), a peer certificate and a valid CertificateVerify are required again before the Finished is accepted, with empty-certificate handling following the configured verify mode (FAIL_IF_NO_PEER_CERT) just as during first-handshake client authentication. Only affects TLS 1.3 servers built with post-handshake authentication support (WOLFSSL_POST_HANDSHAKE_AUTH / --enable-postauth, included in --enable-all) that enable WOLFSSL_VERIFY_POST_HANDSHAKE and request a client certificate after the handshake via wolfSSL_request_certificate(). Clients, and servers that do not use post-handshake authentication, are unaffected.
CVE-2026-11703 Alta · 7.5 CWE-287 25/06/2026
Missing SNI/ALPN binding on stateful (session-ID) TLS session resumption
Missing SNI/ALPN binding on stateful (session-ID) resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual hosts, carry the cached peer-authentication state into a context it was not established for. Resumption now verifies the SNI/ALPN binding for all paths and declines (falling back to a full handshake) on mismatch.
CVE-2026-54089 Crítica · 9.1 CWE-287 25/06/2026
File Browser: bypass de autenticação no modo de autenticação por proxy
File Browser é uma interface de gerenciamento de arquivos para enviar, excluir, visualizar, renomear e editar arquivos dentro de um diretório especificado. A partir da versão 2.0.0-rc.1, quando o FileBrowser é configurado com autenticação por proxy (auth.method=proxy), qualquer atacante não autenticado que consiga acessar o servidor diretamente pode se passar por qualquer usuário, incluindo o administrador, enviando um único cabeçalho HTTP forjado. Nenhuma credencial é necessária. Além disso, informar um nome de usuário inexistente faz o servidor criar automaticamente uma nova conta de usuário, oferecendo um mecanismo de criação de conta sem autorização. Este é um problema já conhecido, documentado na documentação há vários anos, mas não havia sido documentado como vulnerabilidade até agora.
CVE-2026-55759 Alta · 7.4 CWE-287 24/06/2026
Rocket.Chat: Apple Sign-In skips JWT claims validation, allowing expired and cross-audience token replay
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7, and 7.10.13, Rocket.Chat's Apple Sign-In handler verifies JWT signatures but skips claims validation. Any Apple-signed JWT with a non-empty iss is accepted regardless of aud, exp, nbf, or nonce. An attacker who obtains a target user's Apple identity token (from server logs, an intercepted sign-in flow, or another application sharing the same Apple developer team) can replay it to authenticate as that user, with no expiration on the replay window. This vulnerability is fixed in 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7, and 7.10.13.
CVE-2026-55666 Crítica · 9.3 CWE-287 24/06/2026
Rocket.Chat: autenticação inadequada no login OAuth da Apple (CVE-2026-55666)
Rocket.Chat é uma plataforma de comunicação de código aberto, segura e totalmente personalizável. Antes das versões 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7 e 7.10.13, em apps/meteor/app/apple/server/loginHandler.ts, handleIdentityToken analisa um JWT emitido pela Apple durante o fluxo OAuth. O bloco try verifica a presença de um parâmetro de e-mail. Se o JWT não contiver um endereço de e-mail, a aplicação passa a aceitar um valor de e-mail arbitrário fornecido diretamente na requisição. Atacantes conseguem forjar JWTs da Apple que não contêm endereço de e-mail e explorar esta vulnerabilidade para realizar ataques de tomada de conta. Esta vulnerabilidade está corrigida nas versões 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7 e 7.10.13.
CVE-2026-13208 Média · 6.5 CWE-287 24/06/2026
Kubevirt: virt-handler-rhel9: kubevirt: virt-handler notify server trusts vmi identity from unauthenticated grpc request body
A flaw was found in KubeVirt's virt-handler domain notify server. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI identity (namespace/name) solely from the request body without validating it against the connection's origin. Each virt-launcher pod connects through a per-VMI pipe socket, but no identity tag is propagated from the pipe path to the server handlers. This allows a compromised virt-launcher process to send forged domain lifecycle events for any other VMI scheduled on the same node, causing virt-handler to erroneously update that VMI's state and disrupt its lifecycle management.
CVE-2026-56237 Crítica · 9.1 CWE-287 24/06/2026
Autenticação quebrada na geração de chaves de API do Capgo (CVE-2026-56237)
Capgo antes da versão 12.128.2 contém uma vulnerabilidade de autenticação quebrada em seu mecanismo de geração de chaves de API. As chaves de API são expostas em requisições do frontend, e o backend não valida se as chaves são geradas de forma segura e vinculadas ao usuário autenticado. Um atacante pode adulterar o parâmetro da chave de API na requisição de geração e fornecer valores arbitrários, gerando chaves de API personalizadas sem autorização adequada, o que pode levar a acesso não autorizado a endpoints protegidos.
CVE-2026-56223 Alta · 8.7 CWE-287 24/06/2026
Capgo - Account Takeover via Cross-Domain SSO Email Assertion in provision-user
Capgo before 12.128.2 contains a cross-domain SSO account takeover vulnerability in the provision-user endpoint that allows attackers to merge arbitrary victim accounts based on email match without validating SSO provider domain authorization. An attacker with enterprise org admin access and a malicious IdP can forge SAML assertions containing victim email addresses to trigger account merge and gain full access to victim accounts, organizations, and data.
CVE-2026-12112 Alta · 7.8 CWE-287 23/06/2026
Foreman-mcp-server: mcp server: active session hijacking via insecure session state reuse
A flaw was found in the foreman-mcp-server. A session management vulnerability in the MCP Server allows unauthenticated attackers to hijack active administrative sessions due to an improper cache of authenticated client connections, by trusting a non-secret session ID without re-validating authentication tokens and by logging all newly created session IDs to standard logs. This issue can result in privilege escalation and infrastructure-wide code execution.
CVE-2026-54320 Alta · 8.4 CWE-287 23/06/2026
Daytona: Cross-tenant organization takeover via invitation acceptance with an unverified email
Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows. Prior to 0.184.0, organization invitations could be accepted (and declined) by a user whose email matched the invitation but had not been verified. Daytona authenticates users via OIDC and matches an invitation's target email against the email in the caller's token, but the invitation accept and decline paths did not require that email to be verified, unlike organization creation, which already enforced verification. On identity providers that allow self-service signup and issue a session before the email is verified, an actor could register an address matching a pending invitation, leave it unverified, and accept the invitation, joining the target organization with the role the invitation carried (up to Owner). This vulnerability is fixed in 0.184.0.
CVE-2026-52845 Alta · 8.1 CWE-287 23/06/2026
Caddy: FastCGI header normalization bypass in `forward_auth copy_headers`
Caddy is an extensible server platform that uses TLS by default. Prior to 2.11.4, forward_auth copy_headers deletes the exact client-supplied identity header before copying the trusted value from the auth gateway. But when the request later goes through php_fastcgi, Caddy normalizes HTTP headers into CGI variables by replacing - with _. This lets a client send an underscore alias that survives the forward_auth delete step but becomes the same PHP/FastCGI variable. Result: a remote client can inject or sometimes override identity/group headers trusted by PHP/FastCGI applications behind Caddy. This vulnerability is fixed in 2.11.4.

CVE-2026-34917 Média · 4.3 CWE-287 23/06/2026
Improper Authentication em Revive Adserver
Low‑privileged session IDs generated for the web admin console could be reused in the XML‑RPC API, whose authentication is normally restricted to admin users. An attacker could leverage this to gain unauthorised access and exploit API‑level vulnerabilities. The session context (web/API) is now recorded along with other session data, preventing session IDs from being used interchangeably.

CVE-2026-56345 Alta · 8.1 CWE-287 20/06/2026
AVideo - Arbitrary User Session Hijacking via Meet Plugin uploadRecordedVideo Endpoint
AVideo through 29.0 contains an authorization bypass vulnerability in the Meet plugin's uploadRecordedVideo.json.php endpoint that derives the target users_id from the uploaded filename without verification. An attacker with knowledge of the Meet shared secret can craft a malicious file upload with a filename containing an arbitrary users_id to invoke passwordless User->login() and establish an authenticated session as any user including admin. Attackers can obtain the Meet shared secret through path-traversal vulnerabilities or timing attacks against checkToken.json.php, then POST a crafted file to uploadRecordedVideo.json.php with a filename like '1-anything.mp4' to hijack admin sessions and gain full account takeover.
CVE-2026-56294 Média · 4.8 CWE-287 20/06/2026
capacitor-native-biometric - Authentication Bypass via Unvalidated CryptoObject in onAuthenticationSucceeded
capacitor-native-biometric before 12.128.2 contains an authentication bypass vulnerability where the onAuthenticationSucceeded() method fails to validate CryptoObject parameters. Attackers can hook the onAuthenticationSucceeded() function using dynamic instrumentation to bypass biometric authentication without valid credentials.
CVE-2026-56080 Média · 4.9 CWE-287 19/06/2026
Cap-go - Authentication Logic Flaw in Enforce Password Policy
Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.
