CVE-2026-43944
|
| Summary | Electerm users can run dangrous code through link or command line ### Impact _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`._ ### Patches Fixed in version > 3.8.8 commits: - https://github.com/electerm/electerm/commit/8a6a17951e96d715f5a231532bbd8303fe208700 - https://github.com/electerm/electerm/commit/a79e06f4a1f0ac6376c3d2411ef4690fa0377742 - https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507 ### Workarounds - Disable or unregister electerm protocol handlers (Deep Link settings) and avoid clicking `electerm://` links. - Do not run electerm with untrusted `--opts` arguments or open `.lnk` / `.desktop` files from untrusted sources. - Restrict which users can launch electerm on shared machines and avoid leaving electerm installed in locations reachable by other users. - As a temporary measure, run electerm in a confined account or sandbox (non-admin user) to reduce impact. ### References - Report / credit: https://github.com/Curly-Haired-Baboon - Electerm releases: https://github.com/electerm/electerm/releases |
