{"id":"CVE-2026-56248","state":"PUBLISHED","title":"Capgo - Unauthenticated Denial-of-Service via audit_logs RLS Policy","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.","publishedAt":"2026-06-23T12:12:58.643Z","updatedAt":"2026-06-23T13:25:06.551Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Cap-go capgo"],"affected":[{"vendor":"Cap-go","product":"capgo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"12.128.12","versionType":"semver"},{"version":"12.128.12","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/Cap-go/capgo/security/advisories/GHSA-5vgv-rqj5-5748","https://www.vulncheck.com/advisories/capgo-unauthenticated-denial-of-service-via-audit-logs-rls-policy"],"weaknesses":["CWE-400"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/56xxx/CVE-2026-56248.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-56248","state":"PUBLISHED","datePublished":"2026-06-23T12:12:58.643Z","dateUpdated":"2026-06-23T13:25:06.551Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-06-19T21:53:16.001Z"},"containers":{"cna":{"title":"Capgo - Unauthenticated Denial-of-Service via audit_logs RLS Policy","descriptions":[{"lang":"en","value":"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.
