CVE-2026-75569
Full vulnerability record from the local CVENow database.
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.

"value": "Se encontró una vulnerabilidad en mce-operator-bundle. El proceso de compilación obtiene y ejecuta scripts de un repositorio remoto sin realizar comprobaciones de integridad, como el anclaje de commits o la verificación de firmas. Esto permite a un actor malicioso con acceso de escritura al repositorio remoto inyectar y ejecutar código arbitrario durante la compilación. La consecuencia es un proceso de compilación comprometido, lo que podría llevar a la distribución de software malicioso."
