Summary
Yuxi before version 0.6.2 has a flaw in its authentication mechanism: the system does not sufficiently validate the identity token in the Authorization header, only performing a validity check. This allows an administrator token generated in another deployment instance or local testing environment to be used to access the backend management interfaces of a different affected instance.
Risk Assessment
An attacker who obtains or constructs an acceptable administrator token can bypass login, gain administrator privileges, access system configurations, invoke backend management APIs, create administrator accounts, and ultimately take over the system backend.
Recommendation
Update Yuxi to version 0.6.2 or later. Before upgrading, set the environment variable JWT_SECRET_KEY to a non-default value, configure a unique, sufficiently strong JWT/authentication key for each deployment instance, and/or avoid exposing backend management interfaces directly to the public network.

Eval injection vulnerability in hMailServer (versions 6.0.0-6.3.3) allows a remote, unauthenticated attacker to execute arbitrary JScript in the service process with service account privileges. It requires non-default configuration: event scripting enabled, JScript as script language, and an OnClientValidatePassword handler defined. Exploitation uses a password with backslash and apostrophe that is not properly escaped.

A vulnerability in vm2 before 3.12.2 allows an authorization bypass in the NodeVM external-module resolver. When an embedder configures `require.external` with a custom resolver and `context: 'host'`, guest code can require an allowlisted module and then an absolute path of a non-allowlisted sibling sharing the resolved prefix. This leads to a sandbox escape and arbitrary code execution in the host process.

- CVE-2026-82901Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in the 'uacf7_wpcf7_mail_components' function in all versions up to, and including, 3.5.50. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default.
- CVE-2026-85984Critical
The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass via the mo_wp_login_intent parameter in all versions up to, and including, 5.5.5. This is due to a missing password-intent guard in the skip_pass_fallback-enabled configuration branch of the mo_by_pass_login() function, which treats administrator role membership alone as sufficient authentication whenever the unauthenticated, unverified POST parameter mo_wp_login_intent is submitted with the value otp, causing mo_get_user() to skip wp_authenticate_username_password() and resolve a WP_User purely from a username lookup. This makes it possible for unauthenticated attackers to log in as any existing administrator account by supplying only a known username and an empty password alongside mo_wp_login_intent=otp, with no password or OTP verification required. Exploitation is conditional on a site administrator having simultaneously enabled the following plugin options: WP Login OTP, Login with Only OTP, Allow Users to Login with Username and Password, and Admin OTP Bypass.

Original NVD description (English source)
Yuxi is a large-model-based intelligent knowledge base and knowledge graph agent development platform. Prior to version 0.6.2, the project's authentication mechanism contains a flaw. In affected versions, the system does not sufficiently validate the identity token in the Authorization header — only performing a validity check. This allows an administrator token generated in another deployment instance or local testing environment to be used to access the backend management interfaces of a different affected instance. An attacker who obtains or constructs an acceptable administrator Authorization token may bypass normal login authentication and gain administrator privileges. This vulnerability could allow an attacker to access system configurations, invoke backend management APIs, create administrator accounts, and ultimately take over the system backend. This issue has been fixed in version 0.6.2. Before upgrading, users are advised to implement the following temporary measures: Set the environment variable `JWT_SECRET_KEY` to a non-default value, and configure a unique, sufficiently strong JWT/authentication key for each deployment instance; and/or avoid exposing backend management interfaces directly to the public network.
