Detailsinfo

A vulnerability was found in RVC-Project Retrieval-based-Voice-Conversion-WebUI up to 2.2.231006. It has been classified as very critical. This affects the function change_info_. The manipulation of the argument ckpt_path2 with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at securitylab.github.com. This vulnerability is uniquely identified as CVE-2025-43845 since 04/17/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.
