Title
MCPHub: Missing Authorization on `PUT /api/system-config` Lets Any Non-Admin Rewrite Global Security Configuration
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.29, MCPHub's PUT /api/system-config endpoint (handler updateSystemConfig) performs no authorization check. It is protected only by the app-wide authentication middleware and a rate limiter — it never inspects req.user.isAdmin. This issue has been patched in version 1.0.29.

Title
Ech0 before 4.4.3 Authentication Bypass via Comment Panel
Summary
Ech0 before 4.4.3 fails to enforce scope-based authorization on nine comment panel admin endpoints, allowing access tokens with minimal scopes to perform full comment moderation operations. Attackers with a limited-scope access token can list, approve, reject, delete comments, and modify comment system settings by directly accessing the unprotected panel endpoints.

Title
Ech0 before 4.5.1 Authorization Bypass via Session Tokens
Summary
Ech0 before 4.5.1 contains an authorization bypass vulnerability where session tokens skip scope validation in RequireScopes middleware, allowing logged-in non-admin users to access admin endpoints. Attackers can read system logs, visitor statistics, user emails, and subscribe to live WebSocket logs by sending authenticated session tokens to unprotected endpoints.

Title
Keycloak-services: keycloak-services: jwt bearer authorization grant does not enforce consentrequired
Summary
A flaw was found in the JWT Bearer authorization grant implementation within the keycloak-services component of Red Hat Build of Keycloak. This component handles various OAuth2 and OpenID Connect grant types used for issuing access tokens. The issue occurs because the JWT Bearer grant fails to check if a client requires user consent before issuing a token. This allows an authenticated attacker with valid client credentials and a trusted identity provider assertion to bypass the consent requirement and obtain unauthorized access to a user account at a consent-gated client.

Title
RansomLook Missing Authorization in Web Configuration Editor Allows Application Configuration Modification
Summary
RansomLook contains an authorization weakness in the web-based configuration editor exposed through the /admin/config endpoint. The endpoint requires an authenticated session but does not perform an explicit privilege or administrator authorization check before allowing access to configuration-management functionality.
An authenticated low-privileged user able to access the endpoint can submit crafted configuration values that are written directly to the application's config/generic.json file. The affected functionality permits modification of configuration sections including notification, LDAP, SMTP, and general application settings. Successful exploitation could therefore allow an attacker to alter security-sensitive application behavior, redirect integrations or notifications, modify authentication-related configuration, disrupt external services, or render the RansomLook installation unavailable.
The configuration editor also operated on a configuration file containing sensitive values such as passwords, tokens, secrets, and API keys. Although the affected version contains logic intended to prevent recognized secret values from being returned to the browser, exposing configuration management through insufficiently authorized web functionality significantly increases the impact of a compromised or low-privileged account.
The patch resolves the issue by completely removing the /admin/config route and associated configuration-editing interface, preventing application configuration from being modified through the web UI.

Title
Private Group and Market Posts Disclosed Through Public Notification Channels in RansomLook
Summary
RansomLook fails to enforce the privacy status of ransomware groups and markets when distributing newly collected victim posts to external notification channels. The post-processing logic checks whether an individual post is marked private but does not verify whether the group or market to which the post belongs is configured as private.
As a result, newly parsed victim information associated with a private group or market may be automatically published through enabled Rocket.Chat, Mastodon, Bluesky, and e-mail notification channels despite the entity being explicitly configured to prevent public disclosure.
A similar issue affects the public MISP feed. The feed previously determined privacy using groupinfo(), which only queries the group database. Consequently, victim information associated with private markets could be added to the public MISP feed because the corresponding market privacy flag was not evaluated.
An attacker or other unauthorized party able to access these public notification channels or the MISP feed may obtain victim information that was intended to remain private. Depending on the collected data, this may disclose victim names, ransomware activity, incident information, or other information associated with privately monitored groups and markets.
The fix introduces a common is_private_entity() check covering both groups and markets and prevents private entity posts from being distributed through external notification channels or the public MISP feed. Internal storage and dashboard alerting remain unaffected.

Title
RansomLook Missing Authorization Allows Disclosure of Private Group and Ransom Note Data
Summary
RansomLook does not consistently
enforce authorization checks when accessing groups, markets, and ransom
notes marked as private. An unauthenticated or otherwise unauthorized
remote attacker can access information associated with private entities
through several web views and API endpoints.
The affected functionality can
disclose private group or market names, ransom-note content, and
metadata associated with private groups. The /compare
functionality can also be queried directly with the name of a private
entity, allowing an unauthorized user to retrieve information such as
post counts, mirror totals, and uptime even when the entity is excluded
from the normal user interface. The patch explicitly adds a privacy
check before returning this information.
Ransom-note views, search results,
and API endpoints were similarly missing consistent filtering. The fix
introduces normalized private-group identifiers and alias handling, then
rejects or filters notes associated with private groups before
returning them to unauthorized callers.
An attacker can exploit the issue
remotely without authentication or user interaction, resulting in
disclosure of information that was explicitly intended to be restricted
to authorized users.

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.
