Title
Echo: Rejected WebSocket upgrades can bypass Echo route-level access controls
Summary
Echo is a Go web framework. From 4.0.0 until 4.16.1 and 5.4.1, Echo's Proxy middleware selects a raw tunnel from a client WebSocket upgrade request before verifying that the configured upstream accepted the upgrade. If the upstream rejects the upgrade with an ordinary keep-alive response, later HTTP requests on the connection are sent directly to that upstream without passing through Echo's router or route-specific middleware. This can bypass authentication or authorization enforced only by Echo routes, but requires an accessible proxy route, a cooperating rejected-upgrade response, and a target without independent upstream authorization. This issue is fixed in 4.16.1 and 5.4.1.

CVE-2026-117685 (GCVE-0-2026-117685)

Vulnerability from cvelistv5 – Published: 2026-11-01 09:48 – Updated: 2026-11-06 15:25

Title
Gitea public-only package token access to private OCI blobs
Summary
The OCI registry's cross-repository blob mount checked the target package against the token's `public-only` restriction, but checked the source blob only against the full account permissions of the token owner. A `public-only` token with `write:package` scope, whose owner can read a private package and write to a public package namespace, could mount a blob of the private package into the public package. The private blob, such as a container layer, could then be downloaded by anyone through the public package.

CVE-2026-117472 (GCVE-0-2026-117472)

Vulnerability from cvelistv5 – Published: 2026-10-27 05:56 – Updated: 2026-11-04 15:01

Title
URL prefix handling permits API key read-scope bypass in Psono Server
Summary
Psono Server CE && EE versions 4.0.33 through 7.2.3 compared the request path for the bulk-secret-read endpoint with a hard-coded unprefixed path. In deployments configured with URL_PREFIX, the comparison failed and the POST request was authorized using write scope instead of read scope. An authenticated remote attacker with an unusual read-disabled, write-enabled API key could therefore retrieve encrypted secret data and nonces through the prefixed bulk-secret-read endpoint despite lacking read permission. The default configuration without URL_PREFIX was not affected.

Title
NetBox from 2.9.0 before 4.7.4 Authorization Bypass via BulkComponentCreateView
Summary
NetBox from 2.9.0 before 4.7.4 contains a broken access control vulnerability in BulkComponentCreateView that allows authenticated users to bypass view permissions on parent devices and virtual machines. Attackers with add-component permission can submit arbitrary device or VM IDs, or _all with filters, to view out-of-scope device details and create components on them.

CVE-2026-116684 (GCVE-0-2026-116684)

Title
Model Context Protocol Python SDK: Server bearer-token authentication accepts tokens issued for a different resource server
Summary
The Model Context Protocol Python SDK is the official Python SDK for Model Context Protocol servers and clients. From 1.10.0 until 1.30.0 and 2.2.0, server-side bearer authentication configured through AuthSettings with token_verifier accepts a valid token issued for another service when the authorization server serves multiple resources and the TokenVerifier does not independently validate the aud audience. This resource-confusion flaw lets a token holder authenticate to the wrong MCP server and exercise that token's resulting access. This issue is fixed in versions 1.30.0 and 2.2.0.

Title
Neko: Authorization bypass in legacy WebRTC input handling
Summary
Neko is a a self-hosted virtual browser that runs in Docker and uses WebRTC. From version 3.0.0 until 3.1.5, Neko deployments with legacy mode and session.implicit_hosting enabled incorrectly authorize legacy WebRTC data-channel input because LegacyIsHost() evaluates host status incorrectly. An authenticated room member who establishes a WebRTC connection can send mouse and keyboard events through the legacy control channel while controls are locked or the member is otherwise unauthorized by the modern control API. This issue is fixed in version 3.1.5.

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.
