Remote Code Execution in mce-operator-bundle

Publication date: 2026-08-19

Last updated on: 2026-09-07

Assigner: redhat-SADP

Description

A flaw was found in mce-operator-bundle. The build process fetches and executes scripts from a remote repository without performing integrity checks, such as commit pinning or signature verification. This allows a malicious actor with write access to the remote repository to inject and execute arbitrary code during the build. The consequence is a compromised build process, potentially leading to the distribution of malicious software.

Attack-Flow Graph

Executive Summary

This vulnerability is in mce-operator-bundle where the build process fetches and runs scripts from a remote repository without checking their integrity. This means someone with write access to the repository could add malicious code that runs during the build, potentially leading to compromised software being distributed.

Detection Guidance

This vulnerability involves a flaw in the mce-operator-bundle build process where remote scripts are executed without integrity checks. Detection requires verifying the integrity of the build process and scripts used. Check build logs for unexpected script fetches or executions from remote repositories. Inspect the build configuration for missing commit pinning or signature verification. No specific commands are provided in the context.

Impact Analysis

If you use mce-operator-bundle, an attacker could inject malicious code into the build process, resulting in you receiving and running compromised software. This could lead to data breaches, unauthorized access, or other malicious activities on your systems.

Compliance Impact

This vulnerability could lead to unauthorized code execution, potentially violating data protection and privacy requirements under GDPR and HIPAA. Organizations using affected software may face compliance failures, legal penalties, and reputational damage due to compromised data integrity and confidentiality.

Mitigation Strategies

Review and audit the build process for mce-operator-bundle to ensure remote scripts are fetched with integrity checks like commit pinning or signature verification. Remove any untrusted remote repositories from the build pipeline and replace them with trusted sources.
