Summary
Fleet: Unauthenticated Android device disenrollment vulnerability via Pub/Sub endpoint
Details

Summary

A vulnerability in Fleet’s Android MDM Pub/Sub handling could allow unauthenticated requests to trigger device unenrollment events. This may result in unauthorized removal of individual Android devices from Fleet management.

Impact

If Android MDM is enabled, an attacker could send a crafted request to the Android Pub/Sub endpoint to unenroll a targeted Android device from Fleet without authentication.

This issue does not grant access to Fleet, allow execution of commands, or provide visibility into device data. Impact is limited to disruption of Android device management for the affected device.

Workarounds

If an immediate upgrade is not possible, affected Fleet users should temporarily disable Android MDM.

Details

Krayin CRM 2.2.4 contains a missing authentication vulnerability in the installer middleware that allows unauthenticated remote attackers to overwrite the primary administrator account by sending a crafted HTTP POST request with the X-Requested-With: XMLHttpRequest header to bypass the CanInstall middleware redirect check. Attackers can supply arbitrary name, email, and password values to the admin-config-setup endpoint, which performs an unauthenticated updateOrInsert targeting the hardcoded administrator user ID, enabling full administrative access to all CRM data.

Vulnerability from github – Published: 2026-08-05 12:31 – Updated: 2026-08-05 12:31
VLAI
Details

Book-Management-System's Flask API endpoints /student, /record, /books, /find_stu_book, and /find_not_return_book are missing the @login_required decorator that protects sibling routes (/search_student, /storage) in the same file. This allows any unauthenticated remote user to retrieve student PII (name, gender, card validity, debt status) and full book-borrowing history by supplying a card_id. Because card_id values are sequential integers, the entire student database can be enumerated without authentication.

GHSA-9RPW-8VG4-Q84P

Vulnerability from github – Published: 2026-06-12 18:31 – Updated: 2026-06-12 18:31
VLAI
Details

The Aqara Cloud Developer Portal (developer.aqara.com) issued a developer token to any email address supplied by the attacker. This is an instance of "CWE-306: Missing Authentication for Critical Function" with an estimated CVSS of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N (6.5 Medium). When combined with CVE-2026-50083, CVE-2026-50084, and CVE-2026-50085, any otherwise-unauthenticated attacker could execute a full takeover of affected devices.

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.
