An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-70604 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 39.8.10\n- electron (npm): affected all versions; fixed in 39.8.10\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.3\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.3\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.4.0\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.4.0\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0\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-2026-70604/ (Markdown: https://insights.sbomify.com/CVE-2026-70604/index.md)","id":"CVE-2026-70604","markdown":"https://insights.sbomify.com/CVE-2026-70604/index.md","name":"CVE-2026-70604","record":{"aliases":["GHSA-v3j7-r9gq-3gjw"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Remote pages can read sensitive data from custom Electron protocols if CORS is disabled, affecting apps loading untrusted content.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.10, 40.9.3, 41.4.0, and 42.0.0, a custom scheme registered with supportFetchAPI: true but without corsEnabled: true was not subject to CORS enforcement. A page loaded from a remote origin could therefore fetch() or XMLHttpRequest that scheme cross-origin and read the full response body, rather than the read being blocked. Apps that serve sensitive data from such a scheme and load remote or untrusted content in a renderer are affected.
