aws-mcp-server 操作系统命令注入漏洞

aws-mcp-server is a lightweight service developed by Alexei Ledenev. It enables AI assistants to execute AWS CLI commands through the Model Context Protocol MCP in a secure, containerized environment. aws-mcp-server has an operating system command injection vulnerability, which stems from...

Improper Authorization

Overview Affected versions of this package are vulnerable to Improper Authorization via the CloudSpec method on the Controller facade. An attacker can obtain sensitive cloud credentials by making an authenticated API call with only basic login permissions, without requiring elevated privileges...

GHSA-W5FQ-8965-C969 Juju: CloudSpec method leaking cloud credentials

Impact If a user has login permission to a controller and knows the controller model UUID, they can call the CloudSpec method on the Controller facade and get cloud credentials used to bootstrap the controller. The CloudSpec API is called by workers running in the controller to maintain connectio...

Missing Authentication for Critical Function

Overview n8n-mcp is an Integration between n8n workflow automation and Model Context Protocol MCP Affected versions of this package are vulnerable to Missing Authentication for Critical Function due to missing authentication in several HTTP transport endpoints and exposure of sensitive operationa...

GHSA-3WQJ-33CG-XC48 Rembg has a Path Traversal via Custom Model Loading

Summary A path traversal vulnerability in the rembg HTTP server allows unauthenticated remote attackers to read arbitrary files from the server's filesystem. By sending a crafted request with a malicious modelpath parameter, an attacker can force the server to attempt loading any file as an ONNX...

Ech0: Scoped admin access tokens can bypass least-privilege controls on privileged endpoints, including backup export

Summary Ech0 scoped access tokens do not reliably enforce least privilege: multiple privileged admin routes omit scope checks, and the backup export handler strips token scope metadata entirely, allowing a low-scope admin access token to reach broader admin functionality than intended. Impact An...

cpython: Stack overflow parsing XML with deeply nested DTD content models

A stack overflow flaw has been discovered in the python pyexpat module. When an Expat parser with a registered ElementDeclHandler parses an inline document type definition containing a deeply nested content model a C stack overflow occurs. This will result in a program crash...

Anthropic’s Mythos Will Force a Cybersecurity Reckoning—Just Not the One You Think

The new AI model is being heralded—and feared—as a hacker’s superweapon. Experts say its arrival is a wake-up call for developers who have long made security an afterthought...

CVE-2026-40159

PraisonAI is a multi-agent teams system. Prior to 4.5.128, PraisonAI’s MCP Model Context Protocol integration allows spawning background servers via stdio using user-supplied command strings e.g., MCP"npx -y @smithery/cli ...". These commands are executed through Python’s subprocess module. By...

CVE-2026-40086

Rembg is a tool to remove images background. Prior to 2.0.75, a path traversal vulnerability in the rembg HTTP server allows unauthenticated remote attackers to read arbitrary files from the server's filesystem. By sending a crafted request with a malicious modelpath parameter, an attacker can...

CVE-2026-35619

OpenClaw before 2026.3.24 contains an authorization bypass vulnerability in the HTTP /v1/models endpoint that fails to enforce operator read scope requirements. Attackers with only operator.approvals scope can enumerate gateway model metadata through the HTTP compatibility route, bypassing the...

Directory Traversal

Overview rembg is a Remove image background Affected versions of this package are vulnerable to Directory Traversal via the modelpath parameter in the HTTP server for custom model types u2netcustom, discustom, bencustom. An attacker can access arbitrary files on the server's filesystem by sending...

CVE-2026-40159 PraisonAI Exposes Sensitive Environment Variable via Untrusted MCP Subprocess Execution

PraisonAI is a multi-agent teams system. Prior to 4.5.128, PraisonAI’s MCP Model Context Protocol integration allows spawning background servers via stdio using user-supplied command strings e.g., MCP"npx -y @smithery/cli ...". These commands are executed through Python’s subprocess module. By...

CVE-2026-40159

PraisonAI's MCP integration (before 4.5.128) spawns background processes via stdio using user-supplied commands, and forwards the full parent environment to the subprocess. This allows any MCP invocation to inherit sensitive variables (API keys, tokens, database credentials), enabling potential c...
