Description
We've discovered a vulnerability in which attackers could forge HTTP requests to manipulate the charm data directory to access or delete anything on the server. This has been patched in https://github.com/charmbracelet/charm/commit/3c90668f955c7ce5ef721e4fc9faee7053232fd3 and is available in release v0.12.1. We recommend that all users running self-hosted charm instances update immediately.
This vulnerability was found in-house and we haven't been notified of any potential exploiters.
Additional notes
- Encrypted user data uploaded to the Charm server is safe as Charm servers cannot decrypt user data. This includes filenames, paths, and all key-value data.
- Users running the official Charm Docker images are at minimal risk because the exploit is limited to the containerized filesystem.
