Summary

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.

Sources

CVE-2026-52832-PoC-exploit-nuclio-dashboardPoC
Nuclio Dashboard (NOP mode) accepts unauthenticated POST /api/functions. The spec.handler field isn't path-validated, so ../../../../tmp/x.txt:handler escapes the build tempdir via path.Join, letting an attacker write arbitrary content to any path as root. (CVE-2026-52832, ≤1.15.27)
