It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-76802 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/projectdiscovery/nuclei/v3 (Go): affected from 3.0.0; fixed in 3.10.0\n- github.com/projectdiscovery/nuclei/v3 (Go): affected from 3.0.0; fixed in 3.10.0\n- github.com/projectdiscovery/nuclei/v3 (Go): affected from 3.0.0; fixed in 3.10.0\n- github.com/projectdiscovery/nuclei (Go): affected all versions; no fix listed\n- github.com/projectdiscovery/nuclei/v2 (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-76802/ (Markdown: https://insights.sbomify.com/CVE-2026-76802/index.md)","id":"CVE-2026-76802","markdown":"https://insights.sbomify.com/CVE-2026-76802/index.md","name":"CVE-2026-76802","record":{"aliases":["GHSA-jpf4-98qj-qr67","GO-2026-6570"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Vulnerability scanner","requires_auth":"none","summary":"Attackers can execute arbitrary shell commands by supplying malicious templates when DAST mode is enabled, bypassing signature checks.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"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.
