CVE-2026-0653 — Tp-Link Tapo C260 Firmware security vulnerability

High CVSS 7.2

On TP-Link Tapo C260 v1 and D235 v1, a guest‑level authenticated user can bypass intended access restrictions by sending crafted requests to a synchronization endpoint. This allows modification of protected device settings despite limited privileges. An attacker may change sensitive configuration parameters without authorization, resulting in unauthorized device state manipulation but not full code execution.

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.
