It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-102677 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected from 42.3.3; fixed in 42.10.0\n- electron (npm): affected from 42.3.3; fixed in 42.10.0\n- electron (npm): affected from 43.0.0-beta.1; fixed in 43.5.0\n- electron (npm): affected from 43.0.0-beta.1; fixed in 43.5.0\n- electron (npm): affected from 44.0.0-alpha.1; fixed in 44.0.0-beta.6\n- electron (npm): affected from 44.0.0-alpha.1; fixed in 44.0.0-beta.6\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-2026-102677/ (Markdown: https://insights.sbomify.com/CVE-2026-102677/index.md)","id":"CVE-2026-102677","markdown":"https://insights.sbomify.com/CVE-2026-102677/index.md","name":"CVE-2026-102677","record":{"aliases":["GHSA-qmv3-fv6v-rmhq"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Electron framework","requires_auth":"low_privilege","summary":"A compromised renderer can poison the sandboxed preload code cache, allowing execution of arbitrary code in the privileged preload context.","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":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. From 42.3.3 until 42.10.0, 43.5.0, and 44.0.0-beta.6, Electron's sandboxed preload code cache did not verify that a cached entry matched the preload it was served for. A compromised renderer could write attacker-controlled cache data and cause Electron to reuse it for a later load, executing the renderer's code in the more privileged preload context. The issue affects applications that load untrusted content.
