CVE-2026-56220 — Capgo security vulnerability
Capgo before 12.128.2 contains an authorization bypass vulnerability in the public.manifest INSERT policy that allows read-only org members to insert OTA manifest rows. Attackers with read-only org access can inject malicious manifest entries with arbitrary s3_path values that are served to devices via the unauthenticated /updates endpoint, enabling OTA metadata poisoning and potential malicious asset delivery.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
