Supabase Capgo before 12.128.2 contains an authorization bypass vulnerability in the SECURITY DEFINER record_build_time RPC function that allows unauthenticated attackers to insert arbitrary build-time records. Attackers can exploit this by calling POST /rest/v1/rpc/record_build_time with a public API key to poison billing and quota data for any organization, enabling resource exhaustion and cross-tenant billing manipulation.
CVE-2026-56245
This high-severity CVE scores 8.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
