Description
A flaw was found in the Gleam compiler. A malicious direct or transitive git dependency can exploit an improper path validation vulnerability in the Gleam compiler's handling of git dependencies during dependency download. This allows for arbitrary file system modification, including the deletion and creation of directories outside the intended dependency directory, potentially leading to data loss. In certain environments, this could be further leveraged to achieve arbitrary code execution.
