CVE-2023-36815 — Sealos is a Cloud Operating System designed for managing cloud-native applications

High CVSS 8.1

Sealos is a Cloud Operating System designed for managing cloud-native applications. In version 4.2.0 and prior, there is a permission flaw in the Sealos billing system, which allows users to control the recharge resource account `sealos[.] io/v1/Payment`, resulting in the ability to recharge any amount of 1 renminbi (RMB). The charging interface may expose resource information. The namespace of this custom resource would be user's control and may have permission to correct it. It is not clear whether a fix exists.

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.
