Crispy enough to crunch, soft enough to enjoy. A good bake.
Summary
A Helm contributor discovered a vulnerability where a specially crafted Chart.yaml file, along with a linked Chart.lock file, can lead to local code execution when dependencies are updated.
Key quotes
· 2 pulledFields in a Chart.yaml file, that are carried over to a Chart.lock file when dependencies are updated and this file is written, can be crafted in a way that can cause execution if that same content were in a file that is executed (e.g., a bash.rc file or shell script).
If the Chart.lock file is symlinked to one of these files updating dependencies will write the lock file content to the symlinked file.
