Summary
A critical security vulnerability exists in remote cache extensions for common build systems utilizing bucket-based remote cache (such as those using Amazon S3, Google Cloud Storage, or similar object storage) that allows any contributor with pull request privileges to inject compromised artifacts from an untrusted environment into trusted production environments without detection.
The vulnerability exploits a fundamental design flaw in the "first-to-cache wins" principle, where artifacts built in untrusted environments (feature branches, pull requests) can poison the cache used by trusted environments (protected branches, production deployments).
This attack bypasses all traditional security measures including encryption, access controls, and checksum validation because the poisoning occurs during the artifact construction phase, before any security measures are applied.

"value": "Existe una vulnerabilidad de seguridad cr\u00edtica en las extensiones de cach\u00e9 remota para sistemas de compilaci\u00f3n comunes que utilizan cach\u00e9 remota basada en buckets (como los que usan Amazon S3, Google Cloud Storage o almacenamiento de objetos similar). Esta vulnerabilidad permite a cualquier colaborador con privilegios de solicitud de extracci\u00f3n inyectar artefactos comprometidos desde un entorno no confiable en entornos de producci\u00f3n confiables sin ser detectado. Esta vulnerabilidad explota un fallo de dise\u00f1o fundamental en el principio de \"primero en almacenar en cach\u00e9, gana\", seg\u00fan el cual los artefactos compilados en entornos no confiables (ramas de caracter\u00edsticas, solicitudes de extracci\u00f3n) pueden contaminar la cach\u00e9 utilizada por entornos confiables (ramas protegidas, implementaciones de producci\u00f3n). Este ataque elude todas las medidas de seguridad tradicionales, como el cifrado, los controles de acceso y la validaci\u00f3n de sumas de comprobaci\u00f3n, ya que el envenenamiento se produce durante la fase de construcci\u00f3n del artefacto, antes de que se apliquen las medidas de seguridad."
