CVE-2026-76231
Description
A flaw was found in Renovate. Attackers with repository write access can exploit a command injection vulnerability in the hermit manager. This occurs because user-provided dependency names are not properly sanitized when appended to install and uninstall commands. Successful exploitation allows an attacker to execute arbitrary commands on the machine running Renovate.
Statement
This flaw has a MODERATE impact on Renovate. A command injection flaw in Renovate's hermit manager allowed a user with repository write access to execute arbitrary commands on the machine running Renovate by supplying a maliciously named dependency, which was appended to install/uninstall commands without sanitization. The version of Renovate shipped by Red Hat is beyond the upstream fix (40.33.0); the vulnerable hermit-manager code is not present in the shipped version, so Red Hat's product is not affected.
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.
Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
