**Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?** One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

### Summary A command-injection vulnerability lets any attacker who can influence the server_name field of an MCP execute arbitrary OS commands on Windows hosts that run fastmcp install cursor ### Details 1. generate_cursor_deeplink(server_name, …) embeds server_name verbatim in a cursor://…?name= query string. 2. open_deeplink() is invoked with shell=True only on Windows. That calls cmd.exe /c start <deeplink>. 3. Any cmd metacharacter inside server_name (&, |, >, ^, …) escapes the start command and spawns an attacker-chosen process. ### PoC server.py ``` import random from fastmcp import FastMCP mcp = FastMCP(name="test&calc") @mcp.tool def roll_dice(n_dice: int) -> list[int]: """Roll `n_dice` 6-sided dice and return the results.""" return [random.randint(1, 6) for _ in range(n_dice)] if __name__ == "__main__": mcp.run() ``` then run in the terminal: `fastmcp install cursor server.py` ### Impact OS Command / Shell Injection (CWE-78) Every Windows host that runs f...

### Summary FastMCP documentation [covers the scenario](https://gofastmcp.com/integrations/azure) where it is possible to use Entra ID or other providers for authentication. In this context, because Entra ID does not support Dynamic Client Registration (DCR), the FastMCP-hosted MCP server is acting as the authorization provider, as declared in the Protected Resource Metadata (PRM) document hosted on the server. For example, on a local MCP server, it may be hosted here: ```http http://localhost:8000/.well-known/oauth-protected-resource ``` And the JSON representation of the PRM document: ```json { "resource": "http://localhost:8000/mcp", "authorization_servers": [ "http://localhost:8000/" ], "scopes_supported": [ "User.Read", "email", "openid", "profile" ], "bearer_methods_supported": [ "header" ] } ``` Notice that the `authorization_servers` field contains the MCP server itself - it acts as an **OAuth Client** to the downstream authorization ...

Cybersecurity researchers have flagged a new security issue in agentic web browsers like OpenAI ChatGPT Atlas that exposes underlying artificial intelligence (AI) models to context poisoning attacks. In the attack devised by AI security company SPLX, a bad actor can set up websites that serve different content to browsers and AI crawlers run by ChatGPT and Perplexity. The technique has been

BeyondTrust’s annual cybersecurity predictions point to a year where old defenses will fail quietly, and new attack vectors will surge. Introduction The next major breach won’t be a phished password. It will be the result of a massive, unmanaged identity debt. This debt takes many forms: it’s the “ghost” identity from a 2015 breach lurking in your IAM, the privilege sprawl from thousands of new

Organizations in Ukraine have been targeted by threat actors of Russian origin with an aim to siphon sensitive data and maintain persistent access to compromised networks. The activity, according to a new report from the Symantec and Carbon Black Threat Hunter Team, targeted a large business services organization for two months and a local government entity in the country for a week. The attacks

Cybersecurity researchers have discovered a set of 10 malicious npm packages that are designed to deliver an information stealer targeting Windows, Linux, and macOS systems. "The malware uses four layers of obfuscation to hide its payload, displays a fake CAPTCHA to appear legitimate, fingerprints victims by IP address, and downloads a 24MB PyInstaller-packaged information stealer that harvests

Aisuru, the botnet responsible for a series of record-smashing distributed denial-of-service (DDoS) attacks this year, recently was overhauled to support a more low-key, lucrative and sustainable business: Renting hundreds of thousands of infected Internet of Things (IoT) devices to proxy services that help cybercriminals anonymize their traffic. Experts says a glut of proxies from Aisuru and other sources is fueling large-scale data harvesting efforts tied to various artificial intelligence (AI) projects, helping content scrapers evade detection by routing their traffic through residential connections that appear to be regular Internet users.

A group of academic researchers from Georgia Tech, Purdue University, and Synkhronix have developed a side-channel attack called TEE.Fail that allows for the extraction of secrets from the trusted execution environment (TEE) in a computer's main processor, including Intel's Software Guard eXtensions (SGX) and Trust Domain Extensions (TDX) and AMD's Secure Encrypted Virtualization with Secure

### Summary Sliver's custom Wireguard netstack doesn't limit traffic between Wireguard clients, this could lead to: 1. Leaked/recovered keypair (from a beacon) being used to attack operators. 2. Port forwardings usable from other implants. ### Details 1. Sliver treat operators' Wireguard config and beacon/session's Wireguard config equally, they both connect to the wireguard listener created from the CLI. 2. The current netstack implementation does not filter traffic between clients. I think this piece of code handle traffic between clients, from experimental results clients can ping and connect to each other freely, and I didn't see any filtering here either: ``` File: server\c2\wireguard.go 246: func socketWGWriteEnvelope(connection net.Conn, envelope *sliverpb.Envelope) error { 247: data, err := proto.Marshal(envelope) 248: if err != nil { 249: wgLog.Errorf("Envelope marshaling error: %v", err) 250: return err 251: } 252: dataLengthBuf := new(bytes.Buffer) 253: binary.W...
