An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-70612 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 39.8.8\n- electron (npm): affected all versions; fixed in 39.8.8\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.0\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.0\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.2.1\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.2.1\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-beta.3\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-beta.3\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-2026-70612/ (Markdown: https://insights.sbomify.com/CVE-2026-70612/index.md)","id":"CVE-2026-70612","markdown":"https://insights.sbomify.com/CVE-2026-70612/index.md","name":"CVE-2026-70612","record":{"aliases":["GHSA-p2rr-rvmm-c5fp"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Electron framework","requires_auth":"none","summary":"Sandboxed iframes in Electron apps can bypass restrictions to launch external protocol handlers, potentially executing arbitrary OS applications.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, requests to open external protocol URLs from web content did not take iframe sandbox restrictions into account, so a sandboxed iframe could cause an OS-registered external application to be launched. The frame sandbox state was also not made available to the app permission handlers, affecting apps that render untrusted content in sandboxed iframes and grant the openExternal permission by default when no setPermissionRequestHandler is installed.
