CVE-2026-56833— PraisonAI Dynamic Context history and terminal tools read files outside configured storage via path traversal

Quick assessment

Affected

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PraisonAI 是一个多智能体团队系统。在从版本 3.8.1 到 4.6.59 之前（不含 4.6.59）的版本中，PraisonAI 的“动态上下文”（Dynamic Context）模块提供了基于文件系统的历史记录和终端日志存储功能。该模块还导出了可供智能体调用的工具工厂。这些工具接受由调用方传入的 和 参数。底层存储机制将这些参数直接拼接为文件系统路径，却未对绝对路径或 路径遍历进行过滤。由于 可能为绝对路径，而 可能包含路径遍历字符，因此低信任等级的提示或用户若能够调用这些工具，即可读取配置动态上下文基

Vulnerability Title
PraisonAI Dynamic Context history and terminal tools read files outside configured storage via path traversal
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. From version 3.8.1 to before version 4.6.59, PraisonAI's Dynamic Context module provides filesystem-backed history and terminal-log storage. The module also exports agent-callable tool factories. Those tools accept run_id and agent_id arguments from the tool caller. The underlying stores join those values into filesystem paths without rejecting absolute paths or .. traversal. Because run_id can be an absolute path and agent_id can contain traversal, a lower-trust prompt/user that can call these tools can read .jsonl and .log files outside the configured Dynamic Context base directory. This issue has been patched in version 4.6.59.
