CVE-2026-122044 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.8 (high) and affects Hue Bridge Pro; fixed in 6.1.2071524030.

## Summary

Philips Hue Bridge Pro has a flaw in its HTTP service, which listens on TCP port 443 by default, that lets an attacker bypass authentication. An attacker on the same network segment can exploit it without logging in or any user action, gaining the same access as an authenticated user; the bypass is not known to be used in attacks.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Who should check

Anyone running Philips Hue Bridge Pro firmware with the HTTP service on TCP port 443 reachable from an adjacent network.

## Affected

- Philips Hue Bridge Pro: 2071026000

## Description

Philips Hue Bridge Pro Protection Mechanism Failure Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Philips Hue Bridge Pro. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HTTP service, which listens on TCP port 443 by default. The issue results from the failure to apply a protection mechanism. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-33086.

## What to do

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-122044 (Philips Hue Bridge Pro Protection Mechanism Failure Authentication Bypass Vulnerability), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-122044 (entry last updated 2026-11-12):
Affected:
- Philips Hue Bridge Pro: versions 2071026000
Fixed versions: 6.1.2071524030.
Conditions (all must be true for the bug to be hit):
- Philips Hue Bridge Pro with the HTTP service on TCP port 443 (listens on 443 by default) (source: https://www.zerodayinitiative.com/advisories/ZDI-26-892/)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: adjacent access, no login, no user action.
CISA KEV: CVE-2026-122044 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-122044 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.zerodayinitiative.com/advisories/ZDI-26-892/
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
