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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-76804)\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-qgw5-7j4f-fg97","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
