CVE-2026-56226
Capgo (Cap-go/capgo) before 12.128.2 exposes the Supabase PostgREST RPC function public.get_orgs_v6(userid uuid), which is SECURITY DEFINER and granted to the anon role, allowing unauthenticated access. Because the function accepts a caller-supplied user UUID without verifying it matches the authenticated user, an attacker using only the public publishable API key can query POST /rest/v1/rpc/get_orgs_v6 with an arbitrary user UUID to retrieve that user's organization membership, roles, subscription/trial metadata, and management_email (PII).
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data.
- Weakness
- The application reveals information an unauthorised user should not see.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
