## What is CVE-2024-56516?

CVE-2024-56516 is a medium-severity vulnerability in RockChinQ free-one-api, published on 30 Dec 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

free-one-api allows users to access large language model reverse engineering libraries through the standard OpenAI API format. In versions up to and including 1.0.1, MD5 is used to hash passwords before sending them to the backend. MD5 is a cryptographically broken hashing algorithm and is no longer considered secure for password storage or transmission. It is vulnerable to collision attacks and can be easily cracked using modern hardware, exposing user credentials to potential compromise. As of time of publication, a replacement for MD5 has not been committed to the free-one-api GitHub repository.

Weakness: CWE-328 (Use of Weak Hash)

Affected product: RockChinQ free-one-api. 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.
