Prior to 3.11.11, electerm constructs operating system commands in src/app/lib/fs.js by interpolating untrusted file paths into the rmrf(), mv(), and cp() functions. A malicious SSH or SFTP server can provide a filename containing quote characters and shell metacharacters, and a victim can cause that filename to reach the affected operation during remote-to-local transfer, conflict renaming, copying, moving, or removal. The generated `rm -rf`, mv, `cp -r`, PowerShell Remove-Item, Move-Item, or Copy-Item command can then interpret the filename as shell syntax. This allows arbitrary command execution with the electerm desktop user's privileges on POSIX and Windows systems, enabling data exfiltration, file modification, malware installation, or denial of service. This issue is fixed in version 3.11.11.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":null}],"references":["https://github.com/electerm/electerm/security/advisories/GHSA-v5ff-xmfp-p245","https://github.com/electerm/electerm/commit/aa778818843b9c083bd711cd04644d102fcb5a42","https://github.com/electerm/electerm/releases/tag/v3.11.11"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-62420","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 19, 2026, 2:30:12 PM","dateUpdated":"Aug 25, 2026, 2:04:00 AM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
