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.","state":0,"publishedAt":"2026-09-22T16:47:00.36+00:00","modifiedAt":"2026-09-22T17:04:53.745+00:00","affected":[{"ecosystem":"Vendor product","name":"nuclei","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"projectdiscovery\",\n                    \"product\": \"nuclei\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.0.0, < 3.10.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/projectdiscovery/nuclei/security/advisories/GHSA-jpf4-98qj-qr67","https://github.com/projectdiscovery/nuclei/pull/7472","https://github.com/projectdiscovery/nuclei/commit/1c440e755a97471c56fb0276ee8a8c4132974645","https://github.com/projectdiscovery/nuclei/releases/tag/v3.10.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76802","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76802","identifiers":["CVE-2026-76802"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
