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-2026-34767 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 38.8.6\n- electron (npm): affected all versions; fixed in 38.8.6\n- electron (npm): affected from 39.0.0-alpha.1; fixed in 39.8.3\n- electron (npm): affected from 39.0.0-alpha.1; fixed in 39.8.3\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.3\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.8.3\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.0.3\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.0.3\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-2026-34767/ (Markdown: https://insights.sbomify.com/CVE-2026-34767/index.md)","id":"CVE-2026-34767","markdown":"https://insights.sbomify.com/CVE-2026-34767/index.md","name":"CVE-2026-34767","record":{"aliases":["GHSA-4p4r-m79c-wq3v"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Attackers can inject HTTP response headers in Electron apps using custom protocols or webRequest, potentially bypassing security controls like CSP or cookies.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.3, 40.8.3, and 41.0.3, apps that register custom protocol handlers via protocol.handle() / protocol.registerSchemesAsPrivileged() or modify response headers via webRequest.onHeadersReceived may be vulnerable to HTTP response header injection if attacker-controlled input is reflected into a response header name or value. An attacker who can influence a header value may be able to inject additional response headers, affecting cookies, content security policy, or cross-origin access controls. Apps that do not reflect external input into response headers are not affected.
