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）暴露了一个原生构建任务的 TUS 上传代理接口（位于 supabase/functions/_backend/public/build/upload.ts）。该接口仅通过提供的 builder_job_id 对调用者进行单个构建任务的授权验证，并检查该任务所存储的 upload_path，但在后续步骤中，会将用户可控的、从 /build/upload/:jobId/* 路径中提取的 TUS 资源后缀直接转发给构建服务，并同时注入 Capgo 的特权构建 API 密钥。 由于转发的资源

Vulnerability Title
Capgo Build Upload Proxy Authorization Bypass via TUS Resource
来源: CVE Program / CVE List V5
Vulnerability Description
Capgo (capgo.app) exposes a native build TUS upload proxy (supabase/functions/_backend/public/build/upload.ts) that authorizes a caller against a single build job identified by the supplied builder_job_id and validates only that job's stored upload_path, but then forwards the user-controlled TUS resource suffix taken from /build/upload/:jobId/* to the builder service while injecting Capgo's privileged builder API key. Because the forwarded suffix is never bound to the authorized job's upload_path or upload_session_key, a caller holding a valid 'all' or 'write' Capgo API key with app.build_native permission for one application can use its authorized proxy path for job A to write to the TUS upload resource of another job B, provided that resource suffix is known or exposed, corrupting that build's artifacts. All versions are affected; no patch was available at the time of advisory publication.
