Lifecycle Timeline
2DescriptionCVE.org
Capgo (Cap-go/capgo) before 12.128.2 contains an information disclosure vulnerability in the Supabase PostgREST RPC function public.get_total_metrics(org_id), which is callable by the anon role using only the public sb_publishable_* key. An unauthenticated attacker can probe organization existence and leak sensitive usage metrics including MAU, bandwidth, and install counts by sending POST requests to /rest/v1/rpc/get_total_metrics with valid organization UUIDs.
AnalysisAI
Unauthenticated information disclosure in Capgo (Cap-go/capgo) before 12.128.2 exposes sensitive organization metrics through a misconfigured Supabase PostgREST RPC endpoint. The Supabase function public.get_total_metrics(org_id) is accessible to the anon role using only the publicly distributed sb_publishable_* key, meaning any external party can query it without credentials. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond possessing the public sb_publishable_* API key, which is distributed within every Capgo-integrated mobile application and is not a secret credential. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.9 with vector AV:N/AC:L/AT:N/PR:N/UI:N reflects straightforward network-reachable exploitation requiring no authentication and no special conditions, which accurately characterizes this flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker obtains the Capgo sb_publishable_* API key, which is embedded in any Capgo-integrated mobile application and therefore publicly extractable via app decompilation or network traffic inspection. The attacker then sends POST requests to https://[capgo-instance]/rest/v1/rpc/get_total_metrics with sequential or guessed organization UUIDs as the org_id parameter, using the public key in the Authorization header. … |
| Remediation | Upgrade Capgo to version 12.128.2 or later, which is the vendor-confirmed patched release per the advisory at https://github.com/Cap-go/capgo/security/advisories/GHSA-h5jf-xgvh-hgjw. … Detailed patch versions, workarounds, and compensating controls in full report. |
