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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-76802)\n\nAffected packages:\n\n- `github.com/projectdiscovery/nuclei/v3 >= 3.0.0, < 3.10.0`\n\nPatched in:\n\n- `github.com/projectdiscovery/nuclei/v3 3.10.0`\n\nSource: https://github.com/advisories/GHSA-jpf4-98qj-qr67","depth":"sunlit","depthScore":26,"depthScoreParts":{"impact":25.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
