1. 修复分享下载接口越权访问漏洞（高危） - 添加isPathWithinShare函数验证请求路径是否在分享范围内 - 单文件分享只允许下载该文件 - 目录分享只允许下载该目录及子目录的文件 - 防止攻击者通过构造path参数访问分享者的任意文件 - 相关文件：backend/server.js 2. 修复本地存储路径处理问题（中高危） - 优化getFullPath方法处理绝对路径的逻辑 - 修复Linux环境下path.join处理'/'导致的路径错误 - 将绝对路径转换为相对路径，确保正确拼接用户目录 - 相关文件：backend/storage.js 🔐 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
