CVE-2022-29180
Server-Side Request Forgery in charm
Impact
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](https://github.com/charmbracelet/charm/releases/tag/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](https://github.com/charmbracelet/charm/blob/main/docker.md) are at minimal risk because the exploit is limited to the containerized filesystem. ### For more information If you have any questions or comments about this advisory: * Open a [discussion](https://github.com/charmbracelet/charm/discussions) * Email us at [vt100@charm.sh](mailto:vt100@charm.sh) * Chat with us on [Slack](https://charm.sh/slack) * * * <a href="https://charm.sh/"><img alt="the Charm logo" src="https://stuff.charm.sh/charm-badge.jpg" width="400"></a> Charm热爱开源 • Charm loves open source
