Title
argocd-mcp 0.8.0 Authentication Bypass via Unauthenticated HTTP
Summary
argocd-mcp 0.8.0 binds its HTTP transport to every network interface and accepts MCP sessions without requiring caller credentials when ARGOCD_API_TOKEN is configured. Attackers who can reach the listener can invoke the full tool surface using the operator's stored token to create applications, request syncs, and modify Argo CD resources.

CVE-2026-75021 (GCVE-0-2026-75021)

Title
fastify-cli vulnerable to remote code execution via ignored explicit Inspector bind address
Summary
fastify-cli starts the Node.js Inspector when a debug flag is used, but it ignores the explicit bind address the user supplies and binds the Inspector to a broadly reachable address instead of the intended loopback. As a result the debugging interface can be exposed beyond the local machine, and because the Inspector protocol allows arbitrary code evaluation, a remote party that reaches it can achieve remote code execution on the developer's machine. This affects fastify-cli from 1.5.0 up to 8.0.1. Users should upgrade to fastify-cli 8.0.1, which honors the configured Inspector bind address.

CVE-2026-72924 (GCVE-0-2026-72924)

Vulnerability from cvelistv5 – Published: 2026-08-25 21:03 – Updated: 2026-08-26 14:39

Title
GitHub CLI: `gh codespace ports forward` exposes forwarded services on all network interfaces by default
Summary
GitHub CLI (gh) is GitHub's official command line tool. Versions 2.28.0 through 2.97.0 bind the local listener created by gh codespace ports forward to all available network interfaces by default. While port forwarding is active, a service in a Codespace can therefore become reachable through the user's non-loopback local IP addresses by other hosts that can route to the user's machine. This behavior does not change the GitHub-side visibility of the Codespaces port. Instead, it exposes the forwarded service through a wildcard-bound listener on the user's local machine, even when the source Codespaces port remains private. Exploitation requires a network-adjacent attacker to reach the victim's machine while forwarding is active. This issue is fixed in version 2.98.0.

Versions 2.28.0 through 2.97.0 bind the local listener created by gh codespace ports forward to all available network interfaces by default. While port forwarding is active, a service in a Codespace can therefore become reachable through the user\u0027s non-loopback local IP addresses by other hosts that can route to the user\u0027s machine. This behavior does not change the GitHub-side visibility of the Codespaces port. Instead, it exposes the forwarded service through a wildcard-bound listener on the user\u0027s local machine, even when the source Codespaces port remains private. Exploitation requires a network-adjacent attacker to reach the victim\u0027s machine while forwarding is active. This issue is fixed in version 2.98.0."

CVE-2026-55641 (GCVE-0-2026-55641)

Vulnerability from cvelistv5 – Published: 2026-07-10 15:36 – Updated: 2026-07-10 19:06

Title
9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF
Summary
9Router is an AI router & token saver. Prior to 0.5.2, 9router determines whether a /v1 LLM proxy request is local by reading the client-controlled Host header, allowing a remote unauthenticated attacker to send Host: localhost and bypass API-key authentication. In the default configuration, this exposes the /v1 proxy to upstream provider calls using stored provider credentials and allows /v1/search with the searxng provider_options.baseUrl parameter to drive server-side requests to internal or cloud-metadata hosts. This issue is fixed in version 0.5.2.

CVE-2026-42503 (GCVE-0-2026-42503)

Vulnerability from cvelistv5 – Published: 2026-05-06 16:20 – Updated: 2026-05-07 03:55
VLAI
Title
Accidental binding to INADDR_ANY might lead to RCE in golang.org/x/tools/gopls
Summary
gopls by default communicates via pipe. However, -port and -listen flags are supported as means of debugging. If -listen is given a value without an explicit host (e.g. :8080), or -port is used, gopls will listen on 0.0.0.0.  As a result, users might inadvertently cause gopls to bind 0.0.0.0. This can allow a malicious party on the same network to execute code arbitrarily via gopls.

CVE-2026-28395 (GCVE-0-2026-28395)

Title
OpenClaw 2026.1.14-1 < 2026.2.12 - Unintended Public Binding of Chrome Extension Relay via Wildcard cdpUrl
Summary
OpenClaw version 2026.1.14-1 prior to 2026.2.12 contains an improper network binding vulnerability in the Chrome extension (must be installed and enabled) relay server that treats wildcard hosts as loopback addresses, allowing the relay HTTP/WS server to bind to all interfaces when a wildcard cdpUrl is configured. Remote attackers can access relay HTTP endpoints off-host to leak service presence and port information, or conduct denial-of-service and brute-force attacks against the relay token header.

Title
Cisco Nexus 3000 and 9000 Series Switches Silicon One Hardware Abstraction Layer Remote Code Execution Vulnerability
Summary
A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute code with root privileges. This vulnerability exists because TCP ports 43210 and 43211 are accessible in the default Layer 3 (L3) virtual routing and forwarding (VRF). A successful exploit could allow the attacker to connect to an affected device and send crafted input that could be executed as code with root privileges. The exploitation of this vulnerability could also cause the S1HAL process to crash, which could cause the device to reload.

Strategy: Firewall

Unwanted connections to the configured server may be denied through a firewall or other packet filtering measures.

CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
