Unauthenticated network RPC calls using a publicly distributed key (AV:N/AC:L/PR:N/UI:N) leak organization existence and billing status only, so C:H with I:N/A:N and no scope change.

Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains an information disclosure vulnerability in Supabase PostgREST RPC endpoints is_trial_org and is_paying_org that allows unauthenticated attackers to enumerate organizations and disclose billing status using the public sb_publishable key. Attackers can invoke these endpoints to determine organization existence via distinguishable return values and identify paying customers for targeted profiling.
AnalysisAI
Unauthenticated information disclosure in Capgo before 12.128.2 lets remote attackers enumerate organizations and reveal billing status by invoking the Supabase PostgREST RPC endpoints is_trial_org and is_paying_org with the publicly distributed sb_publishable key. The flaw is reachable directly over the network without credentials and produces distinguishable responses that identify paying customers, enabling targeted profiling; no public exploit identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires only network reachability to the affected Capgo Supabase project and possession of the sb_publishable (anon) key, which is publicly distributed inside Capgo client applications and is therefore not a meaningful secret. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) and score of 8.7 correctly model trivial network reachability with no privileges or user interaction and a confidentiality-only impact, which matches the described oracle behaviour. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker extracts the sb_publishable key from the Capgo client bundle or a public app, then scripts POST requests to /rest/v1/rpc/is_trial_org and /rest/v1/rpc/is_paying_org with candidate organization identifiers harvested from GitHub, app stores, or marketing pages. Distinguishable return values reveal which organization names actually exist on Capgo and which are paying customers, producing a target list for phishing, competitive intelligence, or follow-on account takeover attempts. … |
| Remediation | Upgrade Capgo to 12.128.2 or later, which per the GHSA-mh5p-rrhp-442q advisory restricts or removes anon access to the is_trial_org and is_paying_org RPCs (Vendor-released patch: 12.128.2). … Detailed patch versions, workarounds, and compensating controls in full report. |
