Title
Kiteworks Email Protection Gateway Unrestricted Upload of File with Dangerous Type
Summary
An unauthenticated attacker could cause a file with attacker-controlled content to be written to the appliance filesystem through an administrative upload handler that did not properly authenticate the request. This did not by itself result in code execution, which would require a separate vulnerability to place the file in an executable location.

CVE-2026-102121 (GCVE-0-2026-102121)

Vulnerability from cvelistv5 – Published: 2026-09-30 20:17 – Updated: 2026-10-01 13:37
VLAI
Title
Kiteworks Secure Data Forms Exposure of Sensitive Information to an Unauthorized Actor
Summary
A form-rendering interface in the Advanced Forms component is reachable without authentication so that published forms can be displayed to anonymous visitors, but it returned more data than the form itself required. Anyone who knew the web address of a published form could potentially retrieve the form owner's Kiteworks account profile, including personal details, along with parts of the deployment's configuration settings; no passwords, authentication tokens, or multi-factor secrets were exposed.

CVE-2026-102110 (GCVE-0-2026-102110)

Vulnerability from cvelistv5 – Published: 2026-09-30 20:21 – Updated: 2026-10-01 13:37

Title
Missing authentication on a Kiteworks appliance setup function
Summary
An endpoint used during initial appliance setup did not require authentication and did not correctly enforce its intended state precondition, so during the initial activation window an unauthenticated network attacker could repeatedly re-trigger the privileged activation process. This could disrupt setup and leave the appliance in an incompletely configured state. The issue is only reachable while an appliance is being activated for the first time and not yet fully configured.

CVE-2026-101065 (GCVE-0-2026-101065)

Title
Obot Quickstart Docker Deployment Unauthenticated Admin Access
Summary
Obot is an open-source AI agent/MCP platform. In all versions up to and including commit d7e6970, the Docker quickstart command documented in the README starts the container listening on 0.0.0.0:8080 with authentication disabled by default. When authentication is disabled, every request is mapped to a synthetic "nobody" user that holds the Owner and Admin roles, so any unauthenticated party who can reach the exposed port obtains full administrative access to the Obot API and UI, including the ability to register and launch attacker-controlled MCP servers. Because the quickstart also mounts /var/run/docker.sock into the container, the MCP runtime backend reachable this way has access to the host's Docker control surface. The fix is documentation-only: the quickstart now enables authentication, and operators who followed the previous instructions should set OBOT_SERVER_ENABLE_AUTHENTICATION=true before exposing the host to any untrusted network.

Title
notionnext-org NotionNext Authentication Guard cache.js cleanCache missing authentication
Summary
A security vulnerability has been detected in notionnext-org NotionNext up to 4.10.10. Affected by this issue is the function cleanCache of the file pages/api/cache.js of the component Authentication Guard. The manipulation of the argument token leads to missing authentication. The attack may be initiated remotely. Versions 4.1.0 - 4.9.5.2 allow unauthenticated exploitation due to missing method check. In versions 4.9.5.7 - 4.10.10 a guard present but only enforced when CACHE_REVALIDATION_TOKEN is set. Default deployments remain unprotected. The vendor was contacted early about this disclosure but did not respond in any way.

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.
