Capgo - Unauthenticated API Key Validity and Permission Oracle via RPC Functions
Details

Capgo before 12.128.2 contains unauthenticated security definer RPC functions getuserid and getorgpermforapikey that expose API key validity oracles and user UUID disclosure. Unauthenticated attackers using the public API key can validate leaked keys, enumerate users and apps, and determine permission levels, significantly increasing the actionability of compromised credentials.
