Summary

Cloud Commander versions 19.20.2 through 19.21.1 contain a path traversal vulnerability in the GET /api/v1/pack endpoint where the onGET handler calls the unguarded root() function instead of the root.resolve() validation wrapper. Attackers can use percent-encoded directory traversal sequences to read arbitrary files outside the configured --root directory, such as /etc/passwd or SSH private keys, which are archived and streamed back as a downloadable tar.gz file.

Risk Assessment

The risk includes unauthorized access to sensitive system files and private keys, potentially leading to full system compromise and data confidentiality breach.

Recommendation

Immediately update Cloud Commander to a patched version and restrict access to the /api/v1/pack endpoint to trusted users only.

Other vulnerabilities in Cloud Commander

CVE-2026-82460Critical
Cloud Commander before version 19.20.2 contains a directory traversal vulnerability in REST file-operation and markdown endpoints that fails to properly validate path normalization. Attackers can use path traversal sequences to read, write, move, or copy files outside the configured root directory.

Original NVD description (English source)

Cloud Commander (cloudcmd) versions 19.20.2 through 19.21.1 contains a path traversal vulnerability in the GET /api/v1/pack endpoint where the onGET handler at server/rest/index.js:130 calls the unguarded root() function instead of the root.resolve() validation wrapper used elsewhere. Attackers can send percent-encoded directory traversal sequences in the pack request path to read arbitrary files outside the configured --root directory, such as /etc/passwd or SSH private keys, which are archived and streamed back as a downloadable tar.gz file.
