System Documentation

What problem does it solve?

PHP 文件系统操作审计工具聚焦在对文件系统相关操作的安全性分析，特别是路径校验、归一化、落点写入/包含链以及 TOCTOU 等竞态条件的风险，提供可用于证据链的分析结果与利用性证据。

Core Features & Use Cases

  • 目录与权限相关操作的风险点分析：mkdir/chmod/chown/unlink/rmdir/link/symlink/readlink/touch 等操作的潜在安全漏洞。
  • 路径控制与落点链路分析：对路径校验、baseDir 与前缀校验的实际影响进行追踪，评估写入/包含链条的风险。
  • TOCTOU 与竞态分析：识别检查-使用分离模式中的时序漏洞并给出改进建议与可观测证据。

Quick Start

Run this skill on a PHP project to surface filesystem operation risks and generate traceable evidence for TOCTOU and path validation weaknesses.
