CVE-2026-76804

Nuclei: Local File Read via Workflow File-Protocol Gate Bypass

Published Sep 22, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
Nuclei is a vulnerability scanner built on a simple YAML-based DSL. From 3.0.0 until 3.10.0, the workflow template loading path does not enforce the -file capability gate when resolving file: protocol templates referenced by a workflow. An untrusted unsigned workflow can therefore load a file-protocol template and read local files from the scanner host even when the operator has not enabled file templates. The issue affects CLI users running workflows with -w and SDK integrations that accept end-user workflows while relying on the default file-access restriction. This issue is fixed in version 3.10.0.
