Security readout for executives and security teams
Plain-English summary
Capgo versions before 12.128.2 exposed sensitive business metrics through an unauthenticated API path. An outside party with only the public API key could read financial and operational data such as MRR, revenue breakdowns, customer counts, and telemetry. This is a confidentiality issue, not a system takeover issue based on the provided sources.
Executive priority
Treat as high priority where Capgo is internet-facing or stores sensitive commercial metrics. The main business risk is disclosure of revenue, customer, and operational data. Prioritize upgrade and exposure review; no source currently confirms active exploitation.
Technical view
CVE-2026-56238 is a CWE-200 information disclosure in Capgo’s Supabase PostgREST global_stats endpoint. The advisory describes unauthenticated remote access using the public apikey. CVSS v4.0 is 8.7, driven by network reachability, low complexity, no privileges, no user interaction, and high vulnerable-system confidentiality impact.
Likely exposure
Organizations running Capgo before 12.128.2 are the likely exposure group. Risk is highest where the affected PostgREST API is reachable from untrusted networks and uses the public apikey model described in the advisory.
Exploitation context
The sources describe remote unauthenticated data exposure, but do not cite active exploitation. CISA KEV status in the provided bundle is false. The disclosed data could support competitive intelligence, customer targeting, or business-sensitive reconnaissance.
Researcher notes
Evidence is limited to the CVE record, GitHub advisory, and VulnCheck advisory. The provided CVSS vector indicates confidentiality impact only, with no integrity or availability impact. Avoid assuming broader Capgo components are affected beyond the described global_stats PostgREST endpoint.
Mitigation direction
- Upgrade Capgo to version 12.128.2 or later.
- Review the GitHub advisory for vendor-specific remediation guidance.
- Restrict unauthenticated access to sensitive PostgREST data endpoints.
- Review Supabase/PostgREST authorization policies for global_stats exposure.
- Monitor API logs for unexpected anonymous access to global_stats.
Validation and detection
- Inventory all Capgo deployments and record running versions.
- Confirm exposed deployments are on 12.128.2 or later.
- Verify global_stats is not anonymously readable in production.
- Review logs for unusual access to business-metrics endpoints.
- Document any exposed metrics for incident assessment.
