- Summary
- TensorZero: Arbitrary file read and SSRF in TensorZero Gateway's internal object storage endpoint
- Details
-
TensorZero is an open-source LLMOps platform that unifies an LLM gateway, observability, evaluation, optimization, and experimentation. Prior to 2026.6.0, the TensorZero Gateway /internal/objectstorage endpoint accepts a caller-supplied JSON storagepath parameter that dynamically overrides the [objectstorage] configuration. Selecting the filesystem storage type allows arbitrary files on the gateway filesystem to be read, including credential files. Selecting the s3compatible 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.
