## What is CVE-2026-110690?

CVE-2026-110690 is a high-severity path traversal vulnerability in coderaiser cloudcmd, published on 14 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-23 (Relative Path Traversal)

Check this codebase for CVE-2026-110690 and fix it if it is affected.

What it is: CVE-2026-110690 is a high-severity path traversal vulnerability in coderaiser cloudcmd, published on 14 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-110690 in the wild and no public exploit code.

Affected product: coderaiser cloudcmd. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
