Upgrade github.com/gitpod-io/gitpod to 2022.11.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/gitpod-io/gitpod

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-32766, inspect your project dependencies for Github.com/gitpod io/gitpod:

inspect dependencies for github.com/gitpod-io/gitpod

Analyze the terminal output to locate any version of Github.com/gitpod io/gitpod in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2022.11.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Github.com/gitpod io/gitpod, 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

Gitpod before 2022.11.3 allows XSS because redirection can occur for some protocols outside of the trusted set of three (vscode: vscode-insiders: jetbrains-gateway:).
