安全: - 渠道 webhook 入站强制令牌鉴权(恒定时间比较+统一文案),企微签名官方算法; - 报表/概览/systemInfo 端点按 usage:read/audit:read/system:manage 授权; - sso_error 固定错误码;个人渠道令牌仅请求头;工具出站 Dialer.Control 消除 DNS rebinding TOCTOU;新增 channel:read/manage 权限;限流倍数上限 10。 并发/一致性: - 任务上报单条条件 UPDATE 防重放双提交;认领回收过期 claimed 任务; - 审批改先开通后落记录(幂等,无嵌套事务);聊天消息单事务落库; - 会话列表校验 AuthVersion;吊销先 Del 后 SRem;删工具保护调用历史; - rejected 冷却 24h;限流被拒补偿;maintenance 清理限流窗口。 前端/菜单: - 修复 gatewayChildren late-append 导致 reports/tenants/channels 菜单不可见; - 聊天改名 PUT 对齐;渠道编辑清空凭据防串写+启用开关; - 聊天响应防串扰;报表本地时区日期。
