CVE-2026-52832

Nuclio: Unauthenticated path traversal in spec.handler allows arbitrary file write in Dashboard container

Published Sep 2, 2026 CVSS 3.1 · 4.9 Medium EPSS < 1% KEV · Not listed
Description
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.5, Nuclio Dashboard exposes POST /api/functions without authentication by default (NOP auth mode). The spec.handler field (e.g., mymodule:myfunction) is parsed by functionconfig.ParseHandler() which splits on : only — no path validation is applied to the module portion. This issue has been patched in version 1.16.5.
