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-2026-76804 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-2026-76804/ (Markdown: https://insights.sbomify.com/CVE-2026-76804/index.md)","id":"CVE-2026-76804","markdown":"https://insights.sbomify.com/CVE-2026-76804/index.md","name":"CVE-2026-76804","record":{"aliases":["GHSA-qgw5-7j4f-fg97","GO-2026-6574"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vulnerability scanner","requires_auth":"none","summary":"An attacker can read local files from the scanner host by bypassing file-protocol restrictions in untrusted Nuclei workflows.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Nuclei is a vulnerability scanner built on a simple YAML-based DSL. 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.
