An unauthenticated attacker can insert rows into public.build_logs for arbitrary organizations and, because the function uses ON CONFLICT (build_id, org_id) DO UPDATE, can overwrite existing usage/billing records by reusing the same build_id for a target org. This enables cross-tenant tampering of billing build logs and financial-impact denial of service by inflating billable build time."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "Improper Access Control", "cweId": "CWE-284", "type": "CWE"}]}], "affected": [{"vendor": "Cap-go", "product": "capgo", "defaultStatus": "unaffected", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThan": "12.128.2"}, {"version": "12.128.2", "status": "unaffected", "versionType": "semver"}]}], "metrics": [{"cvssV4_0": {"Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "NONE", "attackVector": "NETWORK", "baseScore": 8.7, "baseSeverity": "HIGH", "exploitMaturity": "NOT_DEFINED", "privilegesRequired": "NONE", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "NONE", "valueDensity": "NOT_DEFINED", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N", "version": "4.0", "vulnAvailabilityImpact": "NONE", "vulnConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "vulnerabilityResponseEffort": "NOT_DEFINED"}, "format": "CVSS"}, {"cvssV3_1": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N", "version": "3.1"}, "format": "CVSS"}], "references": [{"url": "https://github.com/Cap-go/capgo/security/advisories/GHSA-42xj-3h9w-26h5", "name": "GHSA Advisory GHSA-42xj-3h9w-26h5", "tags": ["vendor-advisory"]}, {"name": "VulnCheck Advisory: Supabase - Unauthenticated Cross-Tenant Billing Log Tampering via public.record_build_time RPC", "tags": ["third-party-advisory"], "url": "https://www.vulncheck.com/advisories/supabase-unauthenticated-cross-tenant-billing-log-tampering-via-public-record-build-time-rpc"}], "x_generator": {"engine": "vulncheck"}, "credits": [{"lang": "en", "value": "Judel777", "type": "reporter"}]}}}
