# HPE Networking Fabric Composer: missing integrity check lets remote attackers run code

HPE Networking Fabric Composer does not verify the integrity of some data it accepts. A remote attacker with no account can exploit this to execute arbitrary code on the affected system.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Check your HPE Networking Fabric Composer version in the admin UI. HPE's September advisory (HPESBNW05133, a different set of CVEs) fixed 7.3.4 and 7.4.0; whether those versions also fix this CVE is unconfirmed.

## Timeline

- 2026-11-03T20:49:25+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-95749
- 2026-11-03T20:55:11+00:00 analyst — HPE's CVE-2026-95749 bulletin is not yet indexed. HPE's Oct 27 notice HPESBNW05166 says Fabric Composer advisories ship Nov 3 but gives no details (linked as mentions). The Sept advisory HPESBNW05133 (affects <=7.3.3, fixed 7.3.4/7.4.0) was read in part, and this CVE did not appear in the part I read. No affected versions, fix or internet-facing facts confirmed, nothing verified. Recheck once the Nov 3 HPE advisory appears; the CVSS vector in NVD (AV:N/AC:H/PR:N/UI:R) shows user interaction is required and complexity is high.

## From the sources

A missing integrity verification vulnerability exists in HPE Networking Fabric Composer. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code on the affected system.
