Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Withdrawn Advisory This advisory has been withdrawn because the vulnerability does not affect a package in one of the GitHub Advisory Database's [supported ecosystems](https://github.com/github/advisory-database/blob/main/README.md#supported-ecosystems). This link is maintained to preserve external references. ## Original 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.
