Vulnerability from github – Published: 2023-01-19 15:30 – Updated: 2026-04-08 18:32
VLAI
Details

The Events Made Easy plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions related to AJAX actions in versions up to, and including, 2.3.16. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to invoke those functions intended for administrator use. While the plugin is still pending review from the WordPress repository, site owners can download a copy of the patched version directly from the developer's Github at https://github.com/liedekef/events-made-easy

katello: missing repository authorization in content_uploads exposes cross-product content existence
Details

A flaw was found in Katello's of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content.

Vulnerability from github – Published: 2024-06-18 09:31 – Updated: 2025-09-08 12:30
VLAI
Details

When Bazel Plugin in intellij imports a project (either using "import project" or "Auto import") the dialog for trusting the project is not displayed. This comes from the fact that both call the method ProjectBuilder.createProject which then calls ProjectManager.getInstance().createProject. This method, as its name suggests is intended to create a new project, not to import an existing one.  We recommend upgrading to version 2024.06.04.0.2 or beyond for the IntelliJ, CLion and Android Studio Bazel plugins.

Summary
Missing permission check in Jenkins requests-plugin Plugin allows viewing pending requests
Details

Jenkins requests-plugin Plugin 2.2.6 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to view the list of pending requests.

Jenkins requests-plugin Plugin 2.2.7 requires Overall/Administer permission to view the list of pending requests.

The previous sentence originally stated that Overall/Read permission was newly required. This statement was incorrect and has been fixed on 2021-07-05.

GHSA-C4G4-FG7Q-8P3C

Vulnerability from github – Published: 2026-06-29 18:31 – Updated: 2026-06-29 18:31
VLAI
Details

Elide through 7.1.17 fails to enforce @ReadPermission on client-supplied sort expressions in SortingImpl.getValidSortingRules, allowing attackers to sort collections by forbidden fields. Attackers can infer hidden field values through row ordering analysis, leaking relative field ordering across all rows via both JSON:API and GraphQL read paths.

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.
