## What is CVE-2022-29836?

CVE-2022-29836 is a low-severity path traversal vulnerability in SanDisk My Cloud Home, published on 9 Nov 2022. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability was discovered via an HTTP API on Western Digital My Cloud Home; My Cloud Home Duo; and SanDisk ibi devices that could allow an attacker to abuse certain parameters to point to random locations on the file system. This could also allow the attacker to initiate the installation of custom packages at these locations. This can only be exploited once the attacker has been authenticated to the device. This issue affects: Western Digital My Cloud Home and My Cloud Home Duo versions prior to 8.11.0-113 on Linux; SanDisk ibi versions prior to 8.11.0-113 on Linux.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-29836 and fix it if it is affected.

What it is: CVE-2022-29836 is a low-severity path traversal vulnerability in SanDisk My Cloud Home, published on 9 Nov 2022. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-29836 in the wild and no public exploit code.

Affected product: SanDisk My Cloud Home. 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.
