Capgo是CAPGO公司的一个专为CapacitorJS开发者打造的移动应用开发和更新平台。 Capgo 12.128.2之前版本存在权限许可和访问控制问题漏洞，该漏洞源于允许通过PostgREST直接修补public.apps.owner_org，绕过transfer_app()工作流并导致分裂脑所有权，攻击者可更新apps.owner_org同时保持app_versions.owner_org不变，导致旧组织密钥保留版本数据访问权限而新组织密钥控制应用记录。

Vulnerability Title
Capgo - Authorization Bypass in App Ownership Transfer via Direct PostgREST Update
Source: CVE Program / CVE List V5
Vulnerability Description
Capgo before 12.128.2 allows direct patching of public.apps.owner_org through PostgREST, bypassing the transfer_app() workflow and creating split-brain ownership. Attackers can directly update apps.owner_org while leaving app_versions.owner_org unchanged, enabling old-org keys to retain access to version data while new-org keys control the app record.
