Description:

Virtual Engineering Workbench (VEW) is an open-source platform where platform engineers define and publish development environments, and developers provision them on demand through a web portal. We identified CVE-2026-119085, where improper neutralization of special elements used in a template engine in the publishing component of Amazon Virtual Engineering Workbench (VEW) could allow a remote authenticated third party to run arbitrary code with the permissions of the publishing Lambda's IAM role. This could allow access to data and resources across all tenant projects. The code is reachable through a crafted CloudFormation template body containing template engine directives submitted through the product versioning API.

Impacted versions: All commits before c146486 (PR #31, merged 2026-05-04)

Resolution:

This issue has been addressed in commit c146486 (PR #31). We recommend redeploying from the latest version of the main branch and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds:

There is no workaround that removes the issue. Until you redeploy, you can reduce impact by limiting which users can create or update product versions.
