Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains unauthenticated security definer RPC functions get_user_id and get_org_perm_for_apikey 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.
AnalysisAI
Information disclosure in Capgo (Capacitor live-update/OTA platform) before 12.128.2 lets unauthenticated callers abuse two SECURITY DEFINER RPC functions, get_user_id and get_org_perm_for_apikey, reachable with only the public/anon API key. Attackers can confirm whether a leaked API key is valid, resolve user UUIDs, and read the permission level tied to a key, turning otherwise-uncertain credential leaks into actionable, scoped targets. …
