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-2023-39956 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electron (npm): affected all versions; fixed in 22.3.19\n- electron (npm): affected all versions; fixed in 22.3.19\n- electron (npm): affected from 23.0.0-alpha.1; fixed in 23.3.13\n- electron (npm): affected from 23.0.0-alpha.1; fixed in 23.3.13\n- electron (npm): affected from 24.0.0-alpha.1; fixed in 24.7.1\n- electron (npm): affected from 24.0.0-alpha.1; fixed in 24.7.1\n- electron (npm): affected from 25.0.0-alpha.1; fixed in 25.5.0\n- electron (npm): affected from 25.0.0-alpha.1; fixed in 25.5.0\n- electron (npm): affected from 26.0.0-alpha.1; fixed in 26.0.0-beta.13\n- electron (npm): affected from 26.0.0-alpha.1; fixed in 26.0.0-beta.13\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-2023-39956/ (Markdown: https://insights.sbomify.com/CVE-2023-39956/index.md)","id":"CVE-2023-39956","markdown":"https://insights.sbomify.com/CVE-2023-39956/index.md","name":"CVE-2023-39956","record":{"aliases":["GHSA-7x97-j373-85x5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Electron framework","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code by launching Electron apps with a controlled working directory, bypassing ASAR integrity protections.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electron","vendor":"electronjs"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS. Electron apps that are launched as command line executables are impacted.   Specifically this issue can only be exploited if the following conditions are met: 1. The app is launched with an attacker-controlled working directory and 2. The attacker has the ability to write files to that working directory. This makes the risk quite low, in fact normally issues of this kind are considered outside of our threat model as similar to Chromium we exclude Physically Local Attacks but given the ability for this issue to bypass certain protections like ASAR Integrity it is being treated with higher importance.  This issue has been fixed in versions:`26.0.0-beta.13`, `25.4.1`, `24.7.1`, `23.3.13`, and `22.3.19`. There are no app side workarounds, users must update to a patched version of Electron.","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: Out-of-package code execution when launched with arbitrary cwd","id":"CVE-2023-39956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"electronjs:electron","products":["electronjs:electron"],"type":"code_injection","year":"2023"},"n_packages":10,"n_references":1,"next":{"headline":"Path traversal allows tricking the Talk Android app into writing files into it's root directory","id":"CVE-2023-39957"},"packages":[{"ecosystem":"npm","fixed":["22.3.19"],"introduced":["0"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["22.3.19"],"introduced":["0"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["23.3.13"],"introduced":["23.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["23.3.13"],"introduced":["23.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["24.7.1"],"introduced":["24.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["24.7.1"],"introduced":["24.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["25.5.0"],"introduced":["25.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["25.5.0"],"introduced":["25.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["26.0.0-beta.13"],"introduced":["26.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":null,"source":"GHSA-7x97-j373-85x5"},{"ecosystem":"npm","fixed":["26.0.0-beta.13"],"introduced":["26.0.0-alpha.1"],"last_affected":[],"package":"electron","purl":"pkg:npm/electron","source":"GHSA-7x97-j373-85x5"}],"prev":{"headline":"Notes attachment render HTML in preview mode","id":"CVE-2023-39955"},"products":["electron"],"published":"2023-09-06","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":"2024-09-26","vendors":["electron"]},"summary":"Attackers can execute arbitrary code by launching Electron apps with a controlled working directory, bypassing ASAR integrity protections.","url":"https://insights.sbomify.com/CVE-2023-39956/"}
