CVE-2026-44336 Details
Description
PraisonAI is a multi-agent teams system. Prior to version 4.6.34, PraisonAI's MCP (Model Context Protocol) server (praisonai mcp serve) registers four file-handling tools by default — praisonai.rules.create, praisonai.rules.show, praisonai.rules.delete, and praisonai.workflow.show. Each accepts a path or filename string from MCP tools/call arguments and joins it onto ~/.praison/rules/ (or, for workflow.show, accepts an absolute path) with no containment check. The JSON-RPC dispatcher passes params["arguments"] blind to each handler via **kwargs without validating against the advertised input schema. By setting rule_name="../../<some-path>" an attacker walks out of the rules directory and writes any file the running user can write. Dropping a Python .pth file into the user site-packages directory escalates this primitive to arbitrary code execution in any subsequent Python process the user spawns — the next praisonai CLI invocation, an IDE script run, the user's python REPL, or any background Python service. This issue has been patched in version 4.6.34.
A critical vulnerability in PraisonAI's MCP (Model Context Protocol) server, prior to version 4.6.34, allows for arbitrary file writing and subsequent remote code execution. The server registers several file-handling tools that accept path or filename strings without proper validation, enabling attackers to traverse out of the intended directory and write files. By injecting a malicious Python .pth file into the user's site-packages directory, this vulnerability escalates to arbitrary code execution in any future Python process the user initiates. The issue can also be exploited through indirect prompt injection in connected LLMs, without any user intervention beyond normal usage.
Users can update to PraisonAI version 4.6.34 or later, where this vulnerability has been patched.
