CVE-2026-52832
Nuclio: Unauthenticated path traversal in spec.handler allows arbitrary file write in Dashboard container
MEDIUM 4.9EPSS 0.5%
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.
