Background
PraisonAI is an open-source framework designed for building AI agents that can interact with code and perform various tasks, including code search and context retrieval. The FastContext feature within PraisonAI is intended to streamline code searches by defining a workspace path as the root directory for these operations. However, a critical vulnerability exists that allows users to bypass this workspace restriction, potentially exposing sensitive files outside the intended directory.
Vulnerability Detail
The vulnerability arises from the FastContext feature's handling of file paths. Specifically, the FastContextAgent class does not properly validate the paths provided by users, allowing absolute paths and traversal sequences (e.g., '..') to be processed without restriction. This oversight can lead to unauthorized access to files outside the designated workspace, enabling attackers to read sensitive information such as source code, configuration files, and API keys. The technical flaw lies in the lack of path canonicalization and containment checks, which permits the execution of file operations on unintended directories.
How To Fix
Latest published version: 1.7.14 as of 22 Oct 2026
