CVE-2026-61432 — PraisonAI FastContext before 1.6.78 Path Traversal

Affected: MervinPraison PraisonAI

PraisonAI (praisonaiagents) before 1.6.78 contains a path traversal vulnerability in the FastContext feature (praisonaiagents.context.fast). FastContextAgent.execute_tool() prepends the configured workspace_path only for relative paths and neither rejects absolute paths nor canonicalizes joined paths before enforcing workspace containment. As a result, tool arguments or model-generated function calls to grep_search, glob_search, read_file, or list_directory can supply absolute paths or '../' traversal sequences to read, search, and enumerate files outside the intended workspace directory, with file contents returned to the caller or injected into the model's tool-result context.

PYSEC-2026-4268 — PraisonAI: FastContext path resolution permits absolute and traversal reads outside the workspace

Affected: PyPI: praisonaiagents

# FastContext path resolution permits absolute and traversal reads outside the workspace

## Summary

PraisonAI's `praisonaiagents.context.fast` FastContext feature treats `workspace_path` as the root directory for code search, but its model-facing search tools and high-level `read_context()` helper accept absolute paths and `..` traversal paths without checking that the resolved path remains under that workspace. A lower-trust prompt or caller that can influence FastContext tool arguments can read, search, and enumerate files outside the intended project workspace; the resulting file content is then returned to the caller or injected into the model's tool-result context.

## Technical Details

`FastContextAgent` documents `workspace_path` as the "Root directory for searches" and stores it as an absolute path:

```python class FastContextAgent: """Specialized agent for fast parallel code search.

Attributes: workspace_path: Root directory for searches """

def __init__(self, workspace_path: str, ...): self.workspace_path = os.path.abspath(workspace_path) ```

The same class exposes `grep_search`, `glob_search`, `read_file`, and `list_directory` as model function-call tools via `get_tools()`. Those tools are intended to retrieve code context from the configured workspace.

The problem is in `FastContextAgent.execute_tool()`. It prepends `workspace_path` only when the caller supplies a relative path, but it does not reject absolute paths and doe…
