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-2026-70610 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 39.8.9\n- electron (npm): affected all versions; fixed in 39.8.9\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.2\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.9.2\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.2.2\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.2.2\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-beta.4\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-beta.4\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-2026-70610/ (Markdown: https://insights.sbomify.com/CVE-2026-70610/index.md)","id":"CVE-2026-70610","markdown":"https://insights.sbomify.com/CVE-2026-70610/index.md","name":"CVE-2026-70610","record":{"aliases":["GHSA-ff2p-hmqr-hxm4"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Attackers can execute arbitrary code in Electron preload scripts via prototype pollution if apps accept untrusted object arguments without validation.","user_interaction":"not_required","vuln_class":"code_injection"},"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-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.4, objects copied across the contextBridge boundary from untrusted content could carry an attacker-influenced prototype, enabling prototype-pollution-style attacks against preload code despite context isolation being enabled. Apps are only affected if their preload code accepts object arguments from untrusted content and reads properties from them without own-property checks, while apps that only accept primitive arguments or validate object arguments are not affected.
