A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 6 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Since exploitation requires prior low-privileged code execution within a container, mitigating initial access and container escape vulnerabilities is recommended. Monitor vendor advisories for any future patches or official fixes.

Description

A local vulnerability in Philips Hue Bridge Pro allows attackers with low-privileged code execution within a container to modify files on the device. The vulnerability is rated with a low severity score of 3.8 by ZDI. Exploitation requires prior access to execute code in a restricted environment, limiting the attack surface.

Impact

An attacker with limited code execution privileges inside a container can modify files on the Philips Hue Bridge Pro device. This could potentially lead to unauthorized changes in device behavior or persistence mechanisms. However, the requirement for prior code execution and the low CVSS score suggest limited impact and exploitability.

Summary

CVE-2026-118631 is a restricted file write vulnerability in Philips Hue Bridge Pro. An attacker must first gain the ability to execute low-privileged code within a container on the target system to exploit this flaw. Successful exploitation enables modification of files on affected installations. The vulnerability has a CVSS rating of 3.8, indicating low severity. No details on patch availability or fixed versions are provided.
