Title
Taiko AG1000-01A Rev 7.3/8 Authentication Bypass via Web Interface
Summary
Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 contains an authentication bypass vulnerability in the embedded web configuration interface that allows unauthenticated attackers to access internal application pages without any session management or server-side authentication checks. Attackers with network access can directly request internal resources such as index.zhtml, point.zhtml, and log.shtml to gain full administrative read and write access, enabling unauthorized modification of alarm routing, device configuration, and disruption of monitoring and control functions.

CVE-2026-9103 (GCVE-0-2026-9103)

Vulnerability from cvelistv5 – Published: 2026-07-17 18:49 – Updated: 2026-07-23 03:56

Title
Unauthenticated Superuser Token Issuance via Auto-Login Endpoint
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to gain unauthorized access due to improper authentication in the /api/v1/login/auto_login endpoint. The endpoint issues long-lived superuser bearer tokens without requiring authentication when the AUTO_LOGIN configuration is enabled (enabled by default), which may allow an unauthenticated network attacker to obtain full administrative access. Additionally, permissive cross-origin resource sharing (CORS) settings may allow tokens to be exposed to unintended origins, increasing the risk of unauthorized access.

CVE-2026-9033 (GCVE-0-2026-9033)

Vulnerability from cvelistv5 – Published: 2026-08-20 18:31 – Updated: 2026-08-20 18:59
VLAI
Title
Unauthenticated Captive Portal Session Termination and Forced Logout in Omada Gateways
Summary
An unauthenticated attacker with network access to the captive portal service of an affected device can terminate active captive portal sessions, including forcing logout of specific users or clearing all active sessions. Affected users must re-authenticate to regain access.  Successful exploitation may allow termination of individual or all active captive portal sessions, causing temporary service disruption and requiring users to re-authenticate.

CVE-2026-8732 (GCVE-0-2026-8732)

Vulnerability from cvelistv5 – Published: 2026-05-29 05:32 – Updated: 2026-05-29 10:06

Title
WP Maps Pro <= 6.1.0 - Unauthenticated Privilege Escalation via Administrator Account Creation to wpgmp_temp_access_ajax AJAX Action
Summary
The WP Maps Pro plugin for WordPress is vulnerable to Privilege Escalation via Administrator Account Creation in all versions up to, and including, 6.1.0. This is due to the wpgmp_temp_access_ajax AJAX action being registered with wp_ajax_nopriv_ and protected only by a nonce check using the fc-call-nonce nonce, which is publicly embedded into every frontend page via wp_localize_script as the nonce field of the wpgmp_local JavaScript object, rendering the check ineffective as an access control mechanism. This makes it possible for unauthenticated attackers to invoke the wpgmp_temp_access_support handler with check_temp=false, which unconditionally creates a new WordPress user with the hardcoded role of administrator via wp_insert_user() and returns a magic login URL that, when visited, calls wp_set_auth_cookie() to fully authenticate the attacker as the newly created administrator, resulting in complete site takeover.

Mitigation
Architecture and Design
  • Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
  • Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
  • In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation
Architecture and Design
  • Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
  • In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
Implementation System Configuration Operation

When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].

CAPEC-12: Choosing Message Identifier

This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.

CAPEC-166: Force the System to Reset Values

An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.

CAPEC-216: Communication Channel Manipulation

An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.

CAPEC-36: Using Unpublished Interfaces or Functionality

An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.

CAPEC-62: Cross Site Request Forgery

An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
