AI-suggested
Upgrade Nuclei to version 3.10.0 or later, where the issue is fixed. Until then, avoid running untrusted unsigned workflows or workflows that reference file-protocol templates. Operators should be cautious when using the -w option or SDK integrations that accept end-user workflows and rely on default file access restrictions.
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.
