尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
Capgo（capgo.app）在其应用图标更新路径中存在一个授权缺陷。PUT /app/:id 端点接受由用户控制的 值，对其进行标准化处理后，将其存储到 public.apps.icon_url 中，但未验证该图片路径是否属于目标应用自身的图片命名空间（例如 org/{owner_org}/{app_id}/...）。更新 apps.icon_url 会触发 on_app_update 事件，其对应的 Worker 进程读取 record.icon_url 并调用 cleanStoredImageMetadat

Vulnerability Title
Capgo App Icon Update Privilege Escalation via Service-Role Worker
来源: CVE Program / CVE List V5
Vulnerability Description
Capgo (capgo.app) is affected by an authorization flaw in the app icon update path. The PUT /app/:id endpoint accepts a user-controlled `icon` value, normalizes it, and stores it in public.apps.icon_url without verifying that the image path belongs to the target app's own image namespace (e.g. org/{owner_org}/{app_id}/...). Updating apps.icon_url fires the on_app_update trigger, whose worker reads record.icon_url and calls cleanStoredImageMetadata(), which runs with service-role credentials (supabaseAdmin()) and downloads and re-uploads the referenced storage object with upsert: true. As a result, an authenticated holder of an app-limited write API key can cause the privileged worker to rewrite an out-of-scope private image object (for example an organization logo) that the key cannot read or write directly under Supabase Storage RLS. All versions are affected; no patched version was available at the time of the advisory.
