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-2026-102676 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 41.10.6\n- electron (npm): affected all versions; fixed in 41.10.6\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.9.2\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.9.2\n- electron (npm): affected from 43.0.0-alpha.1; fixed in 43.4.1\n- electron (npm): affected from 43.0.0-alpha.1; fixed in 43.4.1\n- electron (npm): affected from 44.0.0-alpha.1; fixed in 44.0.0-beta.5\n- electron (npm): affected from 44.0.0-alpha.1; fixed in 44.0.0-beta.5\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-2026-102676/ (Markdown: https://insights.sbomify.com/CVE-2026-102676/index.md)","id":"CVE-2026-102676","markdown":"https://insights.sbomify.com/CVE-2026-102676/index.md","name":"CVE-2026-102676","record":{"aliases":["GHSA-9qh4-3jw8-366w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Untrusted webview content can enable Node.js integration in workers, bypassing embedder restrictions to execute privileged code.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS.
