CVE-2026-101153: Arista CloudVision path traversal in sensor

CVE-2026-101153 · Severity: high · CVSS 8 · Published 2026-10-06

Arista CloudVision Portal and Sensor are network monitoring and management platforms that collect telemetry data from network infrastructure. An authenticated administrator with high privileges could exploit a path traversal flaw to read unauthorized files from the Sensor system, potentially exposing sensitive configuration data or other protected information stored on the appliance.

Technologies: Arista Cloudvision Portal. Vendors: Arista.

Quick answers

Is CVE-2026-101153 exploited in the wild?
No. Junglewise Threat Intelligence has no report of CVE-2026-101153 being exploited in the wild.
How severe is CVE-2026-101153?
High severity, with a CVSS score of 8, published 6 October 2026.
Which products and versions are affected?
Arista CloudVision Sensor 1.4.2 and below, 1.3.1 and below, all prior releases; Arista Cloudvision Portal 2026.2.0, 2026.1.2 and below, 2025.3.3 and below, 2025.2.3 and below, 2025.1.4 and below, 2024.3.3 and below.
Is there a fix for CVE-2026-101153?
Yes: fixed in CloudVision Portal: 2026.2.1, 2026.1.3 and later; CloudVision Sensor: 1.4.3 and later. Until then: As an interim measure, the sensor component can be stopped using `cvpi stop sensor` to prevent exploitation, though this disables data collection, observability, and segmentation services. The recommended permanent fix is to upgrade to a patched version and rotate the CA certificate post-upgrade. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.
How is CVE-2026-101153 attacked?
It is attacked over the network.
Am I affected by CVE-2026-101153?
Check whether you run Arista CloudVision Sensor or Arista Cloudvision Portal at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • Fixed in: CloudVision Portal: 2026.2.1, 2026.1.3 and later; CloudVision Sensor: 1.4.3 and later

As an interim measure, the sensor component can be stopped using `cvpi stop sensor` to prevent exploitation, though this disables data collection, observability, and segmentation services. The recommended permanent fix is to upgrade to a patched version and rotate the CA certificate post-upgrade.

Technical details

A path traversal vulnerability (CWE-22) in affected CloudVision Portal and Sensor versions allows authenticated users with high privileges to escape directory restrictions and access arbitrary files on the system. The vulnerability requires network access and high-level administrative credentials; no user interaction is needed. An authenticated attacker can extract unintended data from the Sensor, and a fix is available in later versions.
