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 ...

CVE-2026-45018 Chainlit: Command injection via MCP stdio transport allows unauthenticated remote code execution

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...

Chainlit (Python framework for conversational AI applications) is vulnerable to command injection via its MCP stdio transport in versions 2.4.0rc0 through 2.12.0 . When features.mcp.enabled is set to true, the POST /mcp endpoint is exposed without authentication . The validate_mcp_command() funct...

CVE-2026-69263

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the mitigation for CVE-2025-8943 blocked -y and --yes flags on npx, but packages/components/nodes/tools/MCP/core.ts denied only PATH, LDLIBRARYPATH, DYLDLIBRARYPATH, and NODEOPTIONS by exact...

CVE-2026-69263

Flowise (pre-3.1.3) is affected by CVE-2026-69263. The root cause is that npm_config_yes can bypass the environment-variable block on the MCP feature, allowing npx to auto-install and execute a named package when a Custom MCP server is launched. This creates a path to unauthenticated remote code ...
