What is CVE-2022-29180?
CVE-2022-29180 is a medium-severity server-side request forgery vulnerability in charmbracelet charm, published on 7 May 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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 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.
Weakness: CWE-918
