CVE-2026-75569: Mce-operator-bundle: mce-operator-bundle: bundle-generation business logic fetched from mutable stolostron/release@master
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.

Frequently Asked Questions
Who is exposed to this issue?
Organizations that build mce-operator-bundle are exposed, because the vulnerable behavior occurs during bundle generation. Runtime deployments are not identified as the direct execution point in the available information.
What access would an attacker need to exploit it?
An attacker would need write access to the remote repository from which the build process fetches scripts. They could then alter the fetched content so arbitrary code executes during a build.
Are builds affected by default?
The described build process fetches scripts from the mutable stolostron/release@master reference without integrity checks such as commit pinning or signature verification. A build using that process is affected by this trust model.
What can be done if a fix cannot be applied immediately?
Avoid building from the mutable remote reference where possible. Pin the dependency to a known commit and verify the integrity or signature of fetched scripts before they are executed.
How can teams determine whether they may already be affected?
Review bundle-generation build logs and configuration to determine whether scripts were fetched from stolostron/release@master without commit pinning or signature verification. Builds performed using unverified content from that mutable reference should be treated as potentially compromised.
