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.

PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage

CVE-2026-47394 [HIGH] CWE-200 PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage
PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage
# PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage
## Summary
PraisonAI's Dynamic Context Discovery feature exposes artifact helper tools
through `ctx.get_tools()`:
```python
ctx = setup_dynamic_context()
agent = Agent(
instructions="You are a data analyst.",
tools=ctx.get_tools(),
hooks=[ctx.get_middleware()],
)
```
The official documentation describes these helpers as a way for the agent to
explore large tool-output artifacts that were queued by the middleware:
- large tool outputs are saved as artifacts;
- the agent receives compact artifact references; and
- the agent uses `artifact_tail` and `artifact_grep` to explore that data.

## Summary
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`:
> "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… **with no containment check**."
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 i
