{"id":"CVE-2026-43944","aliases":["GHSA-mpm8-cx2p-626q"],"url":"https://o3.security/vulnerability/CVE-2026-43944","summary":"electerm: dangerous code can be run through links or command line","details":"### Impact\n_Arbitrary local code execution via deep links, CLI `--opts`, or crafted shortcuts. Affected users: electerm installs that accept protocol URLs or CLI options (affected versions listed in the original report). Exploit requires clicking a crafted `electerm://...` link or opening a crafted shortcut/command that launches electerm with attacker-controlled `opts`._\n\n### Patches\nFixed in version > 3.8.8\n\ncommits:\n\n- https://github.com/electerm/electerm/commit/8a6a17951e96d715f5a231532bbd8303fe208700\n- https://github.com/electerm/electerm/commit/a79e06f4a1f0ac6376c3d2411ef4690fa0377742\n- https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507\n\n### Workarounds\n- Disable or unregister electerm protocol handlers (Deep Link settings) and avoid clicking `electerm://` links.\n- Do not run electerm with untrusted `--opts` arguments or open `.lnk` / `.desktop` files from untrusted sources.\n- Restrict which users can launch electerm on shared machines and avoid leaving electerm installed in locations reachable by other users.\n- As a temporary measure, run electerm in a confined account or sandbox (non-admin user) to reduce impact.\n\n### References\n- Report / credit: https://github.com/Curly-Haired-Baboon\n- Electerm releases: https://github.com/electerm/electerm/releases","published":"2026-05-08T03:08:09.046Z","modified":"2026-08-12T03:51:22.567017916Z","cvss":null,"epss":{"score":0.00363,"percentile":0.29989,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"electerm","fixedVersion":"3.8.8"}],"fix":{"url":"https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507","label":"electerm/electerm@0599e67"},"references":[{"type":"WEB","url":"https://github.com/electerm/electerm/releases/tag/v3.8.15"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43944.json"},{"type":"ADVISORY","url":"https://github.com/electerm/electerm/security/advisories/GHSA-mpm8-cx2p-626q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43944"},{"type":"FIX","url":"https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507"},{"type":"FIX","url":"https://github.com/electerm/electerm/commit/8a6a17951e96d715f5a231532bbd8303fe208700"},{"type":"FIX","url":"https://github.com/electerm/electerm/commit/a79e06f4a1f0ac6376c3d2411ef4690fa0377742"},{"type":"PACKAGE","url":"https://github.com/electerm/electerm"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:22.567017916Z"}}
