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-2026-102674 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-2026-102674/ (Markdown: https://insights.sbomify.com/CVE-2026-102674/index.md)","id":"CVE-2026-102674","markdown":"https://insights.sbomify.com/CVE-2026-102674/index.md","name":"CVE-2026-102674","record":{"aliases":["GHSA-gr2m-v5gq-v685"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Electron framework","requires_auth":"none","summary":"Attackers can bypass sandbox restrictions in Electron apps by opening windows from sandboxed documents, gaining full application origin access.","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":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-693","name":"Protection Mechanism Failure"},{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5, windows opened from a sandboxed top-level document did not inherit that document's active HTML sandbox restrictions. Untrusted content in a sandboxed top-level document that was permitted to open popups could therefore create a window with the Electron application's full origin instead of the restricted origin intended by the sandbox. Applications that deny such popups with setWindowOpenHandler are not affected.
