## Overview

Nuclei is a vulnerability scanner built on a simple YAML-based DSL. From 3.0.0 until 3.10.0, the DAST template loading branch does not apply the unsigned code-template signature check before accepting a template that contains both a fuzzing: block and an unsigned code: block. When an operator enables -dast, an untrusted multiprotocol template can place an unsigned code request into the execution queue and run arbitrary shell commands even without -code or a valid cryptographic signature. The issue affects CLI DAST scans and SDK integrations that enable DAST while accepting attacker-supplied templates. This issue is fixed in version 3.10.0.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
