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. Attackers with repository write access can craft malicious gleam.toml files to execute arbitrary commands on the machine running Renovate.

Executive Summary

Renovate versions 39.53.0 to 40.33.0 have a command injection flaw in the gleam manager. The depName parameter is added to gleam deps update commands without sanitization. Attackers with repository write access can insert malicious gleam.toml files to run arbitrary commands on the Renovate host machine.

Detection Guidance

Check Renovate logs for suspicious gleam deps update commands or unexpected command executions. Review gleam.toml files in repositories for malicious depName values. Monitor system processes for unauthorized commands spawned by Renovate.

Impact Analysis

If you use affected Renovate versions and an attacker gains repository write access, they could execute arbitrary commands on your Renovate server. This could lead to data theft, system compromise, or further network infiltration depending on the server's permissions.

Compliance Impact

This vulnerability could lead to unauthorized command execution, potentially exposing sensitive data. This may violate GDPR (data protection) or HIPAA (health data security) if personal or health information is compromised due to the breach.

Mitigation Strategies

Upgrade Renovate to version 40.33.0 or later. Restrict repository write access to trusted users. Audit existing gleam.toml files for malicious entries. Implement input validation for depName parameters.
