Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Capgo.app 在 12.264.5 版本之前，在 的 TUS 代理端点中未强制执行上传过期时间或构建生命周期状态检查。 当创建原生构建请求时，系统会在 表中存储一个 时间戳（有效期为 1 小时）以及状态 。然而，该上传代理在转发 POST、PATCH 和 HEAD 请求到内部构建服务之前，仅加载并校验了 、 、 和 ，且仅验证调用者是否拥有该应用的 权限。 因此，只要认证用户持有该应用的 权限，即使已超过存储的上传过期时间，或构建流程已超出上传阶段，该用户仍可继续向构建上传会话写入数据——除非内部构建服务独立

Vulnerability Title
Capgo.app before 12.264.5 Upload Expiry Bypass via build upload
Source: CVE Program / CVE List V5
Vulnerability Description
Capgo.app before 12.264.5 does not enforce upload expiry or build lifecycle state in the /build/upload/:jobId TUS proxy endpoint. When a native build request is created, an upload_expires_at timestamp (one hour) and a 'pending' status are stored in build_requests, but the upload proxy loads only app_id, owner_org, builder_job_id, and upload_path and checks only the app.build_native permission before forwarding POST, PATCH, and HEAD requests to the internal builder. As a result, an authenticated caller holding app.build_native permission for the app can continue writing to the build upload session after the stored expiry has passed or after the build has moved beyond the upload phase, unless the separate builder service independently rejects the request. The issue is fixed in 12.264.5.
