## What is CVE-2023-39964?

CVE-2023-39964 is a high-severity path traversal vulnerability in 1Panel-dev 1Panel, published on 10 Aug 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

1Panel is an open source Linux server operation and maintenance management panel. In version 1.4.3, arbitrary file reads allow an attacker to read arbitrary important configuration files on the server. In the `api/v1/file.go` file, there is a function called `LoadFromFile`, which directly reads the file by obtaining the requested path `parameter[path]`. The request parameters are not filtered, resulting in a background arbitrary file reading vulnerability. Version 1.5.0 has a patch for this issue.

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

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.
