CVE-2026-56339

Name of the Vulnerable Software and Affected Versions Capgo versions prior to 12.128.2

Description An information disclosure issue exists in the Supabase PostgREST SECURITY DEFINER RPC function public.rescind invitation(). Unauthenticated attackers using only a publishable API key can enumerate the existence of organizations. This is possible because the function returns distinct error messages, specifically NO ORG and NO RIGHTS, allowing attackers to identify valid organization IDs. This discovery can be used to facilitate targeted phishing or social engineering campaigns.

Recommendations Update to version 12.128.2 or later.
