CVE-2026-85661: Improper Limitation of a Pathname to a Restricted Directory

excel-mcp-server 0.1.8 fails to enforce path confinement in stdio mode when EXCELFILESPATH is unset, allowing attackers to read and write arbitrary files. Attackers can supply unchecked file paths to read and write tools to access any file accessible to the process...

Name of the Vulnerable Software and Affected Versions goose versions prior to 1.38.0 Description The software executes arbitrary commands from recipe stdio extensions and retry.checks without security inspection. This occurs because the recipe security scan skips these two fields, allowing...

CVE-2026-85623: Improper Control of Generation of Code

goose 1.37.0 executes arbitrary commands from recipe stdio extensions and retry.checks without security inspection. Attackers can distribute malicious recipes that execute shell commands as the user running goose, bypassing the recipe security scan which does not inspect extensions or retry...

Command Injection

Overview chainlit is a Build Conversational AI. Affected versions of this package are vulnerable to Command Injection through the validatemcpcommand flow in backend/chainlit/mcp.py and the /mcp stdio connect handler. An attacker can execute arbitrary OS commands on the server by sending a POST /m...

CVE-2026-45018

Chainlit is a Python framework for building production-ready conversational AI applications. From 2.4.0rc0 until 2.12.0, Chainlit deployments with features.mcp.enabled set to true in .chainlit/config.toml expose the POST /mcp endpoint without requiring authentication. For stdio transport, the...

GHSA-W3FX-MC44-MF6J Chainlit has command injection via MCP stdio transport that allows unauthenticated remote code execution

Am I affected? Only if your deployment sets features.mcp.enabled = true in .chainlit/config.toml. MCP has been disabled by default since v2.7.0, so most Chainlit deployments are not affected. No authentication is required: /mcp is reachable by any client that can open a session. Summary When MCP ...

mcp-shell — Security Disabled by Default in Bare-Binary Deploy Path + Shell Interpreter in Secure-Mode Allowlist

mcp-shell at commit 17ac0eef5c9a5a42b8fb132d3d034973d55a5433 has two issues that together mean neither the default deploy path nor the recommended "secure mode" delivers the restriction they're marketed as providing. Filing these together because the two failure modes bracket the full intended...
