## What is CVE-2023-22813?

CVE-2023-22813 is a low-severity missing authorization vulnerability in SanDisk My Cloud Home Mobile App, published on 8 May 2023. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A device API
endpoint was missing access controls on Western Digital My Cloud OS 5 iOS and Anroid Mobile Apps, My Cloud Home iOS and Android Mobile Apps, SanDisk ibi iOS and Android Mobile Apps, My Cloud OS 5 Web App, My Cloud Home Web App and the SanDisk ibi Web App. Due to a permissive CORS policy
and missing authentication requirement for private IPs, a remote attacker on
the same network as the device could obtain device information by convincing a
victim user to visit an attacker-controlled server and issue a cross-site
request.

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.
