Prior to 2026.6.0, the TensorZero Gateway /internal/object_storage endpoint accepts a caller-supplied JSON storage_path parameter that dynamically overrides the [object_storage] configuration. Selecting the filesystem storage type allows arbitrary files on the gateway filesystem to be read, including credential files. Selecting the s3_compatible storage type causes outbound object-storage requests to attacker-chosen internal or cloud-metadata endpoints. Exploitation requires access to the gateway, which can be authenticated or unauthenticated depending on deployment configuration. This issue is fixed in version 2026.6.0."}, {"lang": "es", "value": "TensorZero es una plataforma LLMOps de c\u00f3digo abierto que unifica una pasarela LLM, observabilidad, evaluaci\u00f3n, optimizaci\u00f3n y experimentaci\u00f3n.

Seleccionar el tipo de almacenamiento filesystem permite que archivos arbitrarios en el sistema de archivos de la pasarela sean le\u00eddos, incluyendo archivos de credenciales.
