Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains a server-side validation bypass vulnerability in organization security settings that allows authenticated org admins to persist invalid security policy state. Attackers can bypass backend validation by directly updating the public.orgs table from the browser, circumventing field-level validation checks for max_apikey_expiration_days and other security-sensitive configuration parameters.
AnalysisAI
Server-side validation bypass in Capgo before 12.128.2 allows authenticated organization administrators to write invalid values directly to the public.orgs database table from the browser, circumventing field-level security policy enforcement for parameters such as max_apikey_expiration_days. The root cause is insufficient server-side enforcement in a Supabase-backed architecture where authenticated clients can interact directly with underlying tables without adequate RLS or server-side validation gates. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active authenticated session with organization administrator-level privileges within the target Capgo tenant - regular org members without admin rights cannot perform the direct table write. … 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:L/UI:N) scores 5.3 (Medium), reflecting network-accessible exploitation with low privileges and low integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated organization administrator opens browser developer tools or an API client and issues a direct Supabase REST or SDK call to write an arbitrary value - such as max_apikey_expiration_days set to 99999 - to the public.orgs table, bypassing the application UI's validation layer entirely. The server accepts the write because no server-side constraint rejects out-of-range values, leaving the organization's API key governance policy silently corrupted. … |
| Remediation | Upgrade Capgo to version 12.128.2 or later, which introduces server-side enforcement for organization security settings and prevents direct client-side writes from bypassing field validation. … Detailed patch versions, workarounds, and compensating controls in full report. |
