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-2026-34769 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 38.8.6\n- electron (npm): affected all versions; fixed in 38.8.6\n- electron (npm): affected from 39.0.0-alpha.1; fixed in 39.8.0\n- electron (npm): affected from 39.0.0-alpha.1; fixed in 39.8.0\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.7.0\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.7.0\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.0.0-beta.8\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.0.0-beta.8\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-2026-34769/ (Markdown: https://insights.sbomify.com/CVE-2026-34769/index.md)","id":"CVE-2026-34769","markdown":"https://insights.sbomify.com/CVE-2026-34769/index.md","name":"CVE-2026-34769","record":{"aliases":["GHSA-9wfr-w7mm-pc7f"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Attackers can inject command-line switches to disable sandboxing if apps spread untrusted input into webPreferences.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-912","name":"Hidden Functionality"},{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS.

Apps that construct webPreferences by spreading untrusted configuration objects may inadvertently allow an attacker to inject switches that disable renderer sandboxing or web security controls. Apps are only affected if they construct webPreferences from external or untrusted input without an allowlist. Apps that use a fixed, hardcoded webPreferences object are not affected.
