No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (VulnCheck) lists Cap-go capgo versions before 12.128.2 as affected, and Cap-go capgo versions 12.128.2 as unaffected. No release containing a fix is confirmed on record.

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.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment).

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 99 of 150 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 1 repeat row among the latest 100 is merged into the row it repeats. The 51 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-56245?
CVE-2026-56245 is a high-severity vulnerability; its CVE record was published on June 24, 2026. Supabase Capgo before 12.128.2 contains an authorization bypass vulnerability in the SECURITY DEFINER recordbuildtime RPC function that allows unauthenticated attackers to insert arbitrary build-time records. Attackers can exploit this by calling POST /rest/v1/rpc/recordbuildtime with a public API…
When was CVE-2026-56245 made public?
CVE-2026-56245 was made public on March 17, 2026: that is the date its CVE record's CNA, VulnCheck, gives for when the vulnerability was made public. The CVE record itself was published on June 24, 2026. EchelonGraph's copy of the record carries a last-modified date of June 25, 2026; the record at its source may have been updated since.
Is CVE-2026-56245 actively exploited?
CVE-2026-56245 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.5% probability of exploitation in the next 30 days (38th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-56245?
CVE-2026-56245 has a CVSS base score of 8.2 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-56245?
No fix for CVE-2026-56245 is confirmed yet. Until one is published, restrict network exposure of the affected system — for example, keep it off the internet or limit it to trusted networks — and watch for a fix. The CVE record's CNA (VulnCheck) lists Cap-go capgo versions before 12.128.2 as affected, and Cap-go capgo versions 12.128.2 as unaffected. No release containing a fix is confirmed on record.
