{"cve":"CVE-2026-54457","nvd":{"published":"2026-08-21T21:17:00.267","modified":"2026-10-14T19:10:00.297","status":"Awaiting Analysis","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-552","CWE-918"],"references":["https://github.com/tensorzero/tensorzero/commit/0abbc838bae3394fe7491dad7009670d4e3b6cf8","https://github.com/tensorzero/tensorzero/releases/tag/2026.6.0","https://github.com/tensorzero/tensorzero/security/advisories/GHSA-824w-x939-6cmc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-54457","score":0.00402,"percentile":0.34129,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-824w-x939-6cmc","url":"https://osv.dev/vulnerability/GHSA-824w-x939-6cmc","summary":"TensorZero Gateway: Arbitrary file read and SSRF in internal object storage endpoint","modified":"2026-07-23T15:11:46.928899331Z","packages":[{"ecosystem":"PyPI","name":"tensorzero","purl":"pkg:pypi/tensorzero","ranges":["<2026.6.0"],"fixed":["2026.6.0"]}]},{"id":"PYSEC-2026-3541","url":"https://osv.dev/vulnerability/PYSEC-2026-3541","summary":"TensorZero Gateway: Arbitrary file read and SSRF in internal object storage endpoint","modified":"2026-07-23T15:00:23.851798535Z","packages":[{"ecosystem":"PyPI","name":"tensorzero","purl":"pkg:pypi/tensorzero","ranges":["<2026.6.0"],"fixed":["2026.6.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
