Workarounds
- Disable or unregister electerm protocol handlers (Deep Link settings) and avoid clicking
electerm://links. - Do not run electerm with untrusted
--optsarguments or open.lnk/.desktopfiles 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.
