The Web3 WordPress plugin before 3.0.0 is vulnerable to an authentication bypass due to incorrect authentication checking in the login flow in functions 'handle_auth_request' and 'hadle_login_request'. This makes it possible for non authenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in versions up to, and including, 6.26.12. This is due to the plugin performing unsafe JWT token processing without verification or validation in the `get_resource_owner_from_id_token` function. This makes it possible for unauthenticated attackers to bypass authentication and gain access to any existing user account - including administrators in certain configurations - or to create arbitrary subscriber-level accounts.

The Web3 – Crypto wallet Login & NFT token gating plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.6.0. This is due to incorrect authentication checking in the 'hidden_form_data' function. This makes it possible for authenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

The WordPress Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 7.6.4. This is due to insufficient encryption on the user being supplied during a login validated through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they know the email address associated with that user. This was partially patched in version 7.6.4 and fully patched in version 7.6.5.

The Miniorange OTP Verification with Firebase plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 3.6.0 due to the insecure 'administrator' default value for the 'default_user_role' option. This makes it possible for unauthenticated attackers to register an administrator user even if the registration form is disabled.

The All-in-One Microsoft 365 & Entra ID / Azure AD SSO Login plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 2.2.5. This makes it possible for unauthenticated attackers to bypass authentication and log in as other users, including administrators.

Authentication Bypass vulnerability in miniOrange OAuth 2.0 client for SSO plugin <= 1.11.3 at WordPress.

Authentication Bypass vulnerability in miniOrange WP OAuth Server plugin <= 3.0.4 at WordPress.

The Miniorange OTP Verification with Firebase plugin for WordPress is vulnerable to Arbitrary User Password Change in versions up to, and including, 3.6.0. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources, and the user current password check is missing. This makes it possible for unauthenticated attackers to change user passwords and potentially take over administrator accounts.

The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) Pro Addon plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 200.3.9. This is due to insufficient verification on the user being returned by the social login token. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username and the user does not have an already-existing account for the service returning the token.

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.

Dell Enterprise SONiC OS, version(s) 4.1.x, 4.2.x, contain(s) a Missing Critical Step in Authentication vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass. This is a critical severity vulnerability so Dell recommends customers to upgrade at the earliest opportunity.

An unsafe default authentication vulnerability exists in the Initial Setup Authentication functionality of Tenda AC6 V5.0 V02.03.01.110. A specially crafted network request can lead to arbitrary code execution. An attacker can browse to the device to trigger this vulnerability.

Multiple Lenze products of the cabinet series skip the password verification upon second login. After a user has been logged on to the device once, a remote attacker can get full access without knowledge of the password.
