Title
FUXA Unauthenticated Remote Arbitrary Scheduler Write
Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. From 1.2.8 through version 1.2.10, an authorization bypass vulnerability in the FUXA allows an unauthenticated, remote attacker to create and modify arbitrary schedulers, exposing connected ICS/SCADA environments to follow-on actions. This has been patched in FUXA version 1.2.11.

CVE-2026-25903 (GCVE-0-2026-25903)

Title
Apache NiFi: Missing Authorization of Restricted Permissions for Component Updates
Summary
Apache NiFi 1.1.0 through 2.7.2 are missing authorization when updating configuration properties on extension components that have specific Required Permissions based on the Restricted annotation. The Restricted annotation indicates additional privileges required to add the annotated component to the flow configuration, but framework authorization did not check restricted status when updating a component previously added. The missing authorization requires a more privileged user to add a restricted component to the flow configuration, but permits a less privileged user to make property configuration changes. Apache NiFi installations that do not implement different levels of authorization for Restricted components are not subject to this vulnerability because the framework enforces write permissions as the security boundary. Upgrading to Apache NiFi 2.8.0 is the recommended mitigation.

Title
PlaciPy has Missing Authorization Checks on Student Management Endpoints (IDOR)
Summary
PlaciPy is a placement management system designed for educational institutions. In version 1.0.0, the GET /api/students/:email PUT /api/students/:email/status, and DELETE /api/students/:email routes in backend/src/routes/student.routes.ts only enforce authentication using authenticateToken but do not enforce authorization. The application does not verify whether the authenticated user owns the student record being accessed, has an administrative / staff role, or is permitted to modify or delete the target student.

CVE-2026-25752 (GCVE-0-2026-25752)

Vulnerability from cvelistv5 – Published: 2026-02-06 19:05 – Updated: 2026-02-09 15:28

Title
FUXA Unauthenticated Remote Arbitrary Device Tag Write
Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An authorization bypass vulnerability in FUXA allows an unauthenticated, remote attacker to modify device tags via WebSockets. Exploitation allows an unauthenticated, remote attacker to bypass role-based access controls and overwrite arbitrary device tags or disable communication drivers, exposing connected ICS/SCADA environments to follow-on actions. This may allow an attacker to manipulate physical processes and disconnected devices from the HMI. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.
Severity
9.3 (Critical)

Title
Zulip: Anonymous File Access After Disabling Spectator Access
Summary
Zulip is an open-source team collaboration tool. Prior to version 11.6, Zulip is an open-source team collaboration tool. From version 1.4.0 to before version 11.6, even after spectator access (enable_spectator_access / WEB_PUBLIC_STREAMS_ENABLED) is disabled, attachments originating from web-public streams can still be retrieved anonymously. As a result, file contents remain accessible even after public access is intended to be disabled. Similarly, even after spectator access is disabled, the /users/me/<stream_id>/topics endpoint remains reachable anonymously, allowing retrieval of topic history for web-public streams. This issue has been patched in version 11.6. This issue has been patched in version 11.6.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
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 authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.

CAPEC-665: Exploitation of Thunderbolt Protection Flaws

An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
