It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-34781 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 39.8.5\n- electron (npm): affected all versions; fixed in 39.8.5\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.5\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.5\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.1.0\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.1.0\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-alpha.5\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.0.0-alpha.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-2026-34781/ (Markdown: https://insights.sbomify.com/CVE-2026-34781/index.md)","id":"CVE-2026-34781","markdown":"https://insights.sbomify.com/CVE-2026-34781/index.md","name":"CVE-2026-34781","record":{"aliases":["GHSA-f37v-82c4-4x64"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Electron framework","requires_auth":"low_privilege","summary":"Attackers can crash Electron applications by placing malformed image data in the system clipboard, causing a null dereference in clipboard.readImage().","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":2.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, apps that call clipboard.readImage() may be vulnerable to a denial of service. If the system clipboard contains image data that fails to decode, the resulting null bitmap is passed unchecked to image construction, triggering a controlled abort and crashing the process. Apps are only affected if they call clipboard.readImage(). Apps that do not read images from the clipboard are not affected. This issue does not allow memory corruption or code execution.
