Description
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.

Remediation
Red Hat statement
This Important vulnerability in Renovate allows for arbitrary command execution on the system running Renovate. Exploitation requires an attacker to possess repository write access and introduce a specially crafted `gleam.toml` file. While requiring local access and specific repository control, successful exploitation can lead to high impact on system confidentiality, integrity, and availability. The version of Renovate shipped by Red Hat is beyond the upstream fix (40.33.0), so Red Hat's products are not affected.
Red Hat mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
