Vulnerability Title
Capgo - Unauthenticated Denial-of-Service via audit_logs RLS Policy
Source: CVE Program / CVE List V5
Vulnerability Description
Cap-go capgo (capgo-backend) before 12.128.12 contains an unauthenticated denial-of-service vulnerability arising from the audit_logs table's Row-Level Security (RLS) policy when accessed via the Supabase PostgREST API. Because the PostgreSQL query planner executes costly logic before RLS rejection, unfiltered queries to the public.audit_logs endpoint using the public anon key consistently trigger statement timeouts (PostgREST error 57014). Under concurrency, this exhausts database resources and causes cascading HTTP 500 failures on unrelated endpoints (e.g. /orgs), resulting in an application-layer denial of service.

Vulnerability Description
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 12.128.12之前版本存在资源管理错误漏洞，该漏洞源于audit_logs表的行级安全(RLS)策略问题，当通过Supabase PostgREST API访问时，由于PostgreSQL查询规划器在RLS拒绝前执行高成本逻辑，对public.audit_logs端点使用public anon键的无过滤查询持续触发语句超时，在高并发下耗尽数据库资源，导致无关端点级联HTTP 500错误，从而造成
