Common Weakness Enumeration

CWE-305

Allowed

Authentication Bypass by Primary Weakness

Abstraction: Base · Status: Draft

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.

167 vulnerabilities reference this CWE, most recent first.

CVE-2026-114230 (GCVE-0-2026-114230)

Title
Apache Qpid Proton C: Potential authentication bypass: regular AMQP frames can be sent as SASL frames
Summary
When dispatching SASL frames to authenticate the peer, Proton will also dispatch AMQP frames if they claim to be SASL frames. This allows authentication bypass. However there will be no user name set so the effects depend on how the application deals with this condition - which otherwise means that authentication has not completed yet. This issue affects Apache Qpid Proton C: through 0.40.0. Users are recommended to upgrade to version 0.41.1, which fixes the issue.

Title
Keycloak-services: keycloak-services: account takeover via stale sso_auth note in organization identity-first login
Summary
A flaw was found in the Organization identity-first login flow of the Keycloak authentication server. Keycloak is an open-source identity and access management solution used to secure modern applications and services. The issue occurs when an attacker who belongs to multiple organizations initiates a login and then switches to a registration or password reset path. During this process, a flag indicating a successful login is not properly cleared when the user is removed from the session. An attacker can then provide a victim's username, and the system incorrectly treats the stale flag as proof of the victim's identity. This allows the attacker to bypass authentication and gain full access to the victim's account and connected applications.

This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure.\n\nThe highest-value action is to ensure the SSO_AUTH re-authentication note is cleared from the authentication session whenever a flow transition strips the authenticated user: upgrade to Red Hat build of Keycloak 26.6.8 (or the fixed Rhbk/Keycloak Rhel/Keycloak Services builds), which clears the lingering SSO_AUTH re-authentication note from the authentication session during login flow transitions such as registration or credential reset, closing all 2 injection vectors (transition to credential reset flow, transition to registration flow). Until patched, this is a concern on Keycloak deployments with the Organization feature enabled and users holding credentials in multiple organizations, so Disable the Organization feature or ensure users cannot hold memberships across multiple organizations. These controls limit blast radius and contain exploitation, but they do not fix the underlying stale authentication state flag defect \u2014 apply the upstream patch to fully remediate."

Title
BMC Helix Network Management 26.3.00 before 26.3.01 Authentication Bypass via SAML Configuration
Summary
BMC Helix Network Management on-prem 26.3.00 before 26.3.01 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as the local administrator with any password when SAML single sign-on is configured. Attackers can submit the administrator username with an arbitrary password on the web login page to obtain a SuperAdmin session, modify device credentials, run device commands, and alter audit records.

Title
Nginx UI: Authentication bypass: password login does not enforce a passkey-only second factor (2FA bypass)
Summary
Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, POST /api/login checks EnabledOTP but does not require a WebAuthn assertion when EnabledPasskey is true and no TOTP secret is configured. A passkey-only account is therefore issued a session after password verification, despite Enabled2FA reporting that the account has a second factor. An attacker who obtains the password can take over the account and reach administrative functionality without the registered passkey. This issue is fixed in version 2.5.0.

Title
Apache MINA SSHD: LDAP injection in sshd-ldap
Summary
Authentication bypass via LDAP injection in component sshd-ldap in Apache MINA SSHD versions 1.2.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5. Apache MINA SSHD is a Java library for client-side and server-side SSH. The optional sshd-ldap component provides support for integrating password and publickey authentication on the server side with an LDAP server. sshd-ldap is an optional component. SSH servers implemented with Apache MINA SSHD are affected only if they use sshd-ldap and do configure it to be used for password of public key authentication. Other Apache MINA SSHD servers are not affected. Lack of escaping LDAP filter metacharacters enabled successful authentication with username "*" and password "*". Users are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue by properly escaping filter parameters according to RFC 4515.

CVE-2026-85500 (GCVE-0-2026-85500)

Vulnerability from cvelistv5 – Published: 2026-09-17 13:09 – Updated: 2026-09-17 18:12
VLAI
Title
`require_confirmed_with` is not enforced on the action and fails open on an unreadable attribute in AshAuthentication
Summary
Authentication Bypass by Primary Weakness vulnerability in team-alembic AshAuthentication allows an unconfirmed user to obtain a session, defeating a mandatory email confirmation requirement. AshAuthentication.Strategy.Password.Actions.check_user/2 decides whether the attribute named by require_confirmed_with is set using a bare is_nil(Map.get(user, value)). When that attribute is not selected on the loaded record Map.get/2 returns %Ash.NotLoaded{}, and when a field policy denies it for the current actor it returns %Ash.ForbiddenField{}. Neither is nil, so the rejection branch is skipped and sign-i require_confirmed_with is enforced in two places, and neither holds in every configuration. sign_in_with_token and register are checked only inside AshAuthentication.Strategy.Password.Actions, not on the action itself, so any caller that invokes the action directly skips the check. An API layer such as AshGraphql or AshJsonApi invokes the action directly, so this applies to the default configuration. Where a check does run it compares the confirmation attribute against nil. That attribute holds %Ash.NotLoaded{} or %Ash.ForbiddenField{} when it sets select_by_default?: false, when an API layer narrows the read's select, or when a field policy hides it from the sign-in actor. Neither struct is nil, so those configurations read every user as confirmed. This issue affects ash_authentication: from 4.3.8 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.14.
