## What is CVE-2023-24804?

CVE-2023-24804 is a medium-severity path traversal vulnerability in ownCloud Android, published on 13 Feb 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

The ownCloud Android app allows ownCloud users to access, share, and edit files and folders. Prior to version 3.0, the app has an incomplete fix for a path traversal issue and is vulnerable to two bypass methods. The bypasses may lead to information disclosure when uploading the app’s internal files, and to arbitrary file write when uploading plain text files (although limited by the .txt extension). Version 3.0 fixes the reported bypasses.

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

Check this codebase for CVE-2023-24804 and fix it if it is affected.

What it is: CVE-2023-24804 is a medium-severity path traversal vulnerability in ownCloud Android, published on 13 Feb 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.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-24804 exists.

Affected product: ownCloud Android. 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.
