## What is CVE-2025-43845?

CVE-2025-43845 is a high-severity code injection vulnerability in RVC-Project Retrieval-based-Voice-Conversion-WebUI, published on 5 May 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Retrieval-based-Voice-Conversion-WebUI is a voice changing framework based on VITS. Versions 2.2.231006 and prior are vulnerable to code injection. The ckpt_path2 variable takes user input (e.g. a path to a model) and passes it to change_info_ function, which opens and reads the file on the given path (except it changes the final on the path to train.log), and passes the contents of the file to eval, which can lead to remote code execution. As of time of publication, no known patches exist.

Weakness: CWE-94 (Improper Control of Generation of Code)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-43845 and fix it if it is affected.

What it is: CVE-2025-43845 is a high-severity code injection vulnerability in RVC-Project Retrieval-based-Voice-Conversion-WebUI, published on 5 May 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-43845 in the wild and no public exploit code.

Affected product: RVC-Project Retrieval-based-Voice-Conversion-WebUI. 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.
