Description
Capgo before 12.128.2 allows non-admin API keys to read webhook signing secrets via Supabase REST due to insufficient row-level security policies on the webhooks table. Attackers can retrieve the webhook secret and forge valid X-Capgo-Signature headers to send authenticated webhook events to configured receivers, breaking webhook authenticity and integrity.
