{"apiVersion":"1.0","identifier":"CVE-2026-54457","description":"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/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.","publishedAt":"2026-08-21T21:17:00","lastModifiedAt":"2026-08-25T14:16:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54457","cvssScore":7.7,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","epssProbability":0.00294,"riskScore":0.79,"affectedProduct":"TensorZero","affectedVersions":"<2026.6.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-54457","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-54457","en":"https://www.redsauce.net/en/cves/CVE-2026-54457","fr":"https://www.redsauce.net/fr/cves/CVE-2026-54457","pt":"https://www.redsauce.net/pt/cves/CVE-2026-54457","de":"https://www.redsauce.net/de/cves/CVE-2026-54457","sk":"https://www.redsauce.net/sk/cves/CVE-2026-54457","el":"https://www.redsauce.net/el/cves/CVE-2026-54457"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-54457"}}
