      "value": "PraisonAI is a multi-agent teams system. Prior to version 4.6.40, the fix for GHSA-9mqq-jqxf-grvw / CVE-2026-44336 is incomplete. The original advisory description named four vulnerable handlers in `mcp_server/adapters/cli_tools.py`. Commit `68cc9427` (\"fix(security): harden MCP rules path handling…\") added a `_resolve_rule_path()` helper and applied it to `rules.create`, `rules.show`, and `rules.delete`. `workflow.show` was left unchanged. Two adjacent handlers in the same file have the same pattern, `workflow.validate` and `deploy.validate`. Neither was mentioned in the original advisory. Both remained  unchanged. The original advisory also identified the dispatcher (`server.py:281-298`) as a root cause. It accepts unvalidated `**kwargs` from `params[\"arguments\"]` with no enforcement against the tool's declared `input_schema`. That code is unchanged prior to version 4.6.40. A single unauthenticated MCP `tools/call` to `praisonai.workflow.show` returns the contents of any file the host user can read: `/etc/passwd`, `~/.ssh/id_rsa`, `~/.aws/credentials`, or any project `.env`. Version 4.6.40 contains an updated fix."

      "value": "PraisonAI es un sistema de equipos multiagente. Antes de la versión 4.6.40, la corrección para GHSA-9mqq-jqxf-grvw / CVE-2026-44336 está incompleta. La descripción del aviso original nombró cuatro manejadores vulnerables en “mcp_server/adapters/cli_tools.py”. El commit “68cc9427” (’fix(security): harden MCP rules path handling...’) añadió una función auxiliar “_resolve_rule_path()” y la aplicó a “rules.create”, “rules.show”, y “rules.delete”. “workflow.show” se dejó sin cambios. Dos manejadores adyacentes en el mismo archivo tienen el mismo patrón, “workflow.validate” y “deploy.validate”. Ninguno de los dos fue mencionado en el aviso original. Ambos permanecieron sin cambios. El aviso original también identificó el despachador (“server.py:281-298”) como una causa raíz. Acepta “kwargs” no validados de “params[’arguments’]” sin aplicación de restricciones contra el “input_schema” declarado de la herramienta. Ese código está sin cambios antes de la versión 4.6.40. Una única llamada “tools/call” de MCP no autenticada a “praisonai.workflow.show” devuelve el contenido de cualquier archivo que el usuario del host pueda leer: “/etc/p4ssd”, “~/.ssh/id_rsa”, “~/.aws/credentials”, o cualquier archivo “.env” del proyecto. La versión 4.6.40 contiene una corrección actualizada."
