实证状态: `triage-manual` - 实证方式: `synthetic` - Artifact 模式: `synthetic` - 最近运行: `-` - 浏览器证据: `missing` - Run Bundle: `-` ## 事件层 - Canonical ID: `angular--CVE-2026-32635` - 系统: `angular` - 严重度: `medium` - 来源置信度: `official` - 官方主源: https://github.com/angular/angular/security/advisories/GHSA-g93w-mfhg-p222 - 影响版本: `introduced=22.0.0-next.0, fixed<22.0.0-next.3, introduced=21.0.0-next.0, fixed<21.2.4, introduced=20.0.0-next.0.0.0, fixed<20.3.18, introduced=19.0.0-next.0, fixed<19.2.20, introduced=17.0.0-next.0, last_affected=18.2.14` - 修复版本: `22.0.0-next.3, 21.2.4, 20.3.18, 19.2.20` ## 对象与版本映射 - Advisory Scope: `package` - 影响对象: `angular / core` - Entity Refs: `angular, angular--package--angular-core` - 版本置信度: `high` - 版本缺口: `-` - 版本证据源: `https://github.com/angular/angular/security/advisories/GHSA-g93w-mfhg-p222, https://nvd.nist.gov/vuln/detail/CVE-2026-32635, https://github.com/angular/angular/pull/67541, https://github.com/angular/angular/pull/67561, https://github.com/angular/angular/commit/224e60ecb1b90115baa702f1c06edc1d64d86187` ## 受控验证流程 - Workflow ID: `angular--CVE-2026-32635--workflow` - 漏洞家族: `xss` - 入口面: `web-ui-render-path` - 需要角色: `editor-or-admin` - 触发向量: 对 `xss` 家族入口投递最小化、可审计、可回滚的受控输入，比较修复前后差异。 - 请求/页面入口: `/admin/editor, /preview, /rendered-content` - 输入形态: 受控 HTML/Markdown/富文本输入，观察渲染上下文是否失去编码或净化。 - 预期不安全行为: 输入在目标上下文执行或被浏览器解释为主动内容。 ## 其他来源 - https://nvd.nist.gov/vuln/detail/CVE-2026-32635 - https://github.com/angular/angular/pull/67541 - https://github.com/angular/angular/pull/67561 -

基线截图与攻击后截图的 DOM/视觉差异 - console、network 与 response metadata 中的异常信号 ### 数据库/文件系统证据点 - 数据库中新增/越权读取的测试数据 - 文件系统中新增上传样本、缓存条目或越权读取痕迹 ### 检测信号 - WAF / reverse proxy 异常日志、访问日志和告警 - 应用审计日志中的权限错误、重定向异常、模板渲染或上传落盘事件 ### 补丁验证步骤 - 确认目标版本从 `introduced=22.0.0-next.0, fixed<22.0.0-next.3, introduced=21.0.0-next.0, fixed<21.2.4, introduced=20.0.0-next.0.0.0, fixed<20.3.18` 升级或回移到 `22.0.0-next.3`。 - 保留同一组受控输入，在修复前后分别执行并比对响应、日志与浏览器证据。 - 确认修复后仅保留预期业务行为，不再触发越权、回显、异常渲染或错误请求。 - 补充 `xss` 族自动化回归，避免同类路径在插件、主题或代理链中回归。 ### 实验安全备注 - 只使用回环地址、哨兵目标、无害样本或可回滚测试数据。 - 禁止造成持久破坏、越权下载真实数据或不可回滚 side effect。 - 如需浏览器证据，保留 baseline / proof 两份快照以及 console / network 记录。 ## 实验层 - 仅用于自有资产、测试环境或已明确授权目标。 - 允许公网可达目标，但必须满足资产归属或明确授权前提。 - 最小化验证方式: 最小化验证、只读探测、可审计回显、受控注入。 - 若该案例涉及插件、模块或扩展，应同时检查供应链与升级策略。 - 禁止场景: 无归属证明或无明确授权的公网目标；知名公共网站或与测试无关的第三方资产；会造成持久破坏、数据越权下载或不可回滚影响的动作 ## 修复示例 - [javascript-typescript:xss-output-encoding](/Users/x/websafe/05-defense/secure-code/javascript-typescript/xss-output-encoding.md) -
