Overview

projen is a CDK for software projects

Affected versions of this package are vulnerable to Arbitrary Code Execution. Users of projen's NodeProject project type (including any project type derived from it) include a .github/workflows/rebuild-bot.yml workflow that may allow any GitHub user to trigger execution of un-trusted code in the context of the main repository (as opposed to that of a fork). In some situations, such untrusted code may potentially be able to commit to the main repository.
