What is CVE-2026-42453?

Termix, a web-based server management platform, has a vulnerability in its file management operations that could allow an attacker to execute arbitrary shell commands on the remote SSH host. This issue arises from the incorrect use of double-quoted strings for command construction in the extractArchive and compressFiles endpoints within file-manager.ts. Unlike other file manager operations that employ single-quote escaping, the flawed design permits command injection via $(command) substitution. Users are advised to upgrade to version 2.1.0 to mitigate this security risk.

Affected Version(s)

Termix < 2.1.0
