{"id":"CVE-2026-76802","summary":"Nuclei: Arbitrary Command Execution via DAST Code Signature Bypass","details":"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.","aliases":["GHSA-jpf4-98qj-qr67"],"modified":"2026-09-23T03:46:47.134710542Z","published":"2026-09-22T16:47:00.360Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76802.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76802.json"},{"type":"FIX","url":"https://github.com/projectdiscovery/nuclei/commit/1c440e755a97471c56fb0276ee8a8c4132974645"},{"type":"FIX","url":"https://github.com/projectdiscovery/nuclei/pull/7472"},{"type":"WEB","url":"https://github.com/projectdiscovery/nuclei/releases/tag/v3.10.0"},{"type":"ADVISORY","url":"https://github.com/projectdiscovery/nuclei/security/advisories/GHSA-jpf4-98qj-qr67"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76802"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectdiscovery/nuclei","events":[{"introduced":"990cec0de154bd3955e0c1e19951f90e06f6ea7c"},{"fixed":"f9cf234c12a333656751e04493dc4b1f4f5f3e88"}],"database_specific":{"extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.10.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.9.0","v3.8.0","v3.7.1","v3.7.0","v3.5.1","v3.5.0","v3.4.10","v3.4.9","v3.4.8","v3.4.7","v3.4.6","v3.4.5","v3.4.4","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.10","v3.3.9","v3.3.8","v3.3.7","v3.3.6","v3.3.5","v3.3.4","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.9","v3.2.8","v3.2.7","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.10","v3.1.9","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-76802.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
