## 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 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.

## Affected products

- 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
