- Severity: CVSS 6.7 (Medium), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2022.8.857.0, 2022.8.936, 2022.8.861.0
- Published: 2022-10-28 · Updated: 2025-05-05

## Affected

- Cloudflare WARP: fixed in 2022.8.857.0
- Cloudflare WARP: fixed in 2022.8.936
- Cloudflare WARP: fixed in 2022.8.861.0

## Description

It was possible to bypass policies configured for Zero Trust Secure Web Gateway by using warp-cli 'set-custom-endpoint' subcommand. Using this command with an unreachable endpoint caused the WARP Client to disconnect and allowed bypassing administrative restrictions on a Zero Trust enrolled endpoint.

## What to do

- Check your stack: if you ship or depend on Cloudflare WARP, upgrade to a fixed version (2022.8.857.0, 2022.8.936, 2022.8.861.0) per the references below.
