Renovate versions from 39.53.0 before 40.33.0 contain a command injection vulnerability in the gleam manager where the depName parameter is appended to gleam deps update commands without proper sanitization. Attackers with repository write access can craft malicious gleam.toml files to execute arbitrary commands on the machine running Renovate.
