CVE-2026-88888

Description

A flaw was found in Renovate. Attackers can exploit a command injection vulnerability in the Mix manager by injecting shell metacharacters through malicious package names when processing private dependencies with unescaped organization parameters. This allows for the execution of arbitrary commands as the Renovate user in binarySource=docker mode.

Statement

Moderate: This command injection flaw in Renovate's Mix manager allows an attacker to execute arbitrary commands as the Renovate user. This occurs when processing private dependencies with unescaped organization parameters in binarySource=docker mode, limiting the attack surface to specific configurations within Red Hat Konflux environments.

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.
