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.

Workaround

The vulnerability resides within the build process of `mce-operator-bundle`, specifically concerning the fetching of build logic from a mutable source without integrity verification. As this issue pertains to the build-time integrity of the software, there are no direct runtime configuration or operational controls available for users to mitigate this vulnerability in deployed Red Hat products.
