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-2026-70606 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.10.6\n- electron (npm): affected from 40.0.0-alpha.1; fixed in 40.10.6\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.9.1\n- electron (npm): affected from 41.0.0-alpha.1; fixed in 41.9.1\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.5.1\n- electron (npm): affected from 42.0.0-alpha.1; fixed in 42.5.1\n- electron (npm): affected from 43.0.0-alpha.1; fixed in 43.0.0\n- electron (npm): affected from 43.0.0-alpha.1; fixed in 43.0.0\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-2026-70606/ (Markdown: https://insights.sbomify.com/CVE-2026-70606/index.md)","id":"CVE-2026-70606","markdown":"https://insights.sbomify.com/CVE-2026-70606/index.md","name":"CVE-2026-70606","record":{"aliases":["GHSA-r4w5-6pfg-jxp5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Electron framework","requires_auth":"none","summary":"Electron apps using custom protocol handlers may leak cached data across isolated sessions if the session is not explicitly specified in the response.","user_interaction":"required","vuln_class":"information_disclosure"},"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:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 40.10.6, 41.9.1, 42.5.1, and 43.0.0, when a custom protocol handler returned a ProtocolResponse with a url and no session, Electron made the upstream request through defaultSession instead of the session that handled the protocol. A cached response could then be reused across otherwise isolated session partitions. Apps that use ProtocolResponse.url, omit ProtocolResponse.session, and rely on separate sessions to isolate content are affected. This issue is fixed in versions 40.10.6, 41.9.1, 42.5.1, and 43.0.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Electron: ProtocolResponse.url reuses the default session cache instead of the registering session","id":"CVE-2026-70606","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"electronjs:electron","products":["electronjs:electron"],"type":"information_disclosure","year":"2026"},"n_packages":8,"n_references":1,"next":{"headline":"Electron: window.open features string controls some window options considered privileged","id":"CVE-2026-70607"},"packages":[{"ecosystem":"npm","fixed":["40.10.6"],"introduced":["40.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["40.10.6"],"introduced":["40.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["41.9.1"],"introduced":["41.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["41.9.1"],"introduced":["41.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["42.5.1"],"introduced":["42.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["42.5.1"],"introduced":["42.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["43.0.0"],"introduced":["43.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-r4w5-6pfg-jxp5"},{"ecosystem":"npm","fixed":["43.0.0"],"introduced":["43.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-r4w5-6pfg-jxp5"}],"prev":{"headline":"Electron: HTTP redirect followed into local file loader","id":"CVE-2026-70605"},"products":["electron"],"published":"2026-08-05","related":[{"cvss_score":9.8,"headline":"Chromium Remote Code Execution in electron","id":"CVE-2017-16151","kev_date_added":null,"published":"2018-06-07"},{"cvss_score":8.8,"headline":"Electron protocol handler browser vulnerable to Command Injection","id":"CVE-2018-1000118","kev_date_added":null,"published":"2018-03-07"},{"cvss_score":8.4,"headline":"Electron: Context Isolation bypass via contextBridge VideoFrame transfer","id":"CVE-2026-34780","kev_date_added":null,"published":"2026-04-04"},{"cvss_score":8.3,"headline":"Electron: \u003cwebview\u003e can enable Node.js integration in Web Workers despite embedder restrictions","id":"CVE-2026-102676","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.2,"headline":"Electron drops inherited HTML sandbox restrictions for popups opened through OpenURLFromTab","id":"CVE-2026-102673","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.2,"headline":"Electron: Windows opened from a sandboxed top-level document do not inherit its sandbox restrictions","id":"CVE-2026-102674","kev_date_added":null,"published":"2026-09-29"},{"cvss_score":8.1,"headline":"Electron: Use-after-free in offscreen child window paint callback","id":"CVE-2026-34774","kev_date_added":null,"published":"2026-04-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["electron"]},"summary":"Electron apps using custom protocol handlers may leak cached data across isolated sessions if the session is not explicitly specified in the response.","url":"https://insights.sbomify.com/CVE-2026-70606/"}
